- [Narrator] Adolf Hitler believed

he possessed superhuman qualities.

In public, he claimed he'd never been ill in his life.

- Hitler was a complete hypochondriac.

- [Narrator] But in private,

he was hiding a terrible secret

he had to keep covered up for his entire life.

- As a member of the master Aryan race,

there was a strong bias against congenital problems.

- [Narrator] By the time the most destructive war

of the 20th century turned against his aggressor,

he could no longer hide the illness

that was attacking his body.

- He drools, he can't keep his arms,

now what they were picking up

was of course the escalation of his Parkinson's.

- [Narrator] And Hitler's drug fueled madness

was taking its toll.

- He had become a drug addict,

Hitler just degenerated and became this raving sick guy.

- [Narrator] This is the truth behind the propaganda

and lies about the 20th century's most hated man.

- In reality, Hitler became a human wreck.

(people shouting)

- [Narrator] Adolf Hitler has been described

as a grotesque figure,

hollow chested with thin and spindly legs, narrow shoulders,

flabby flesh and brown, rotten teeth, a drug addict,

insane and delusional.

(speaking in foreign language)

But Adolf Hitler claimed to be one of the hardest men

Germany had seen for decades,

equipped with the greatest authority of any German leader.

And the Reich Propaganda Ministry

went to great lengths to promote this myth.

- [Announcer] Significant.

- [Narrator] A leader who worked tirelessly for his people,

a non-smoker and a vegetarian.

(dramatic music)

As with many aspects of Hitler's public life,

his sex life, his family life,

his public image was an invention.

Heil Hitler, meaning healthy Hitler,

sound of body, sound of mind,

was a well worked propaganda message

to promote the power of the Führer.

- It was an important part of the cult

that the party created around Hitler

to portray him as basically a health saint.

He was always shown and presented as an abstinent person.

People knew that the Führer doesn't drink alcohol.

He doesn't eat meat.

He walks with his dog every day.

He's in the clear mountain air.

- [Narrator] Hitler's glorified public persona

belied his deep narcissism and many ailments.

He complained of skin irritations,

stomach problems and explosive flatulence.

According to US military medical reports,

Hitler regularly took over 82 medications while in power.

When Hitler's physician, Dr. Theodor Morell,

suggested he write up his medical history,

drug addled Hitler said he'd never been ill,

so there was nothing to write about.

By the time the end came,

Hitler no longer had a clear understanding

of what was happening to him,

as a terminal illness ravaged his failing body.

His drug addled brain

didn't seem to be able to grasp the enormity

of what he and his Nazi party had inflicted on the world.

(plane whirring)

On April the 30th, 1945,

as allied forces converged on German cities,

in a bunker under the chancellery in Berlin,

Hitler took his own life.

(dramatic music)

Days later, fragments of Hitler's body

were recovered by the Red Army.

Since Hitler's death,

vast resources have been poured

into the forensic examination of what remains of Hitler.

Can forensic examination of remnants of Hitler's skull,

medical notes, and personal accounts

help explain the evil of Adolf Hitler.

In 2017, Russian authorities permitted a team of researchers

to examine what was left of Hitler.

Hitler's teeth indicated cyanide poisoning

and confirmed he was on a vegetarian diet.

Hitler was 56 when he died and he had only five

of his own teeth left.

Over the years, historians and researchers

have analyzed Hitler's mental health.

An examination of Hitler's physical health

relies on accounts from his inner circle, his physicians,

as well as the fragments of his burnt body.

Apart from the discovery of rotten teeth,

Hitler may have been predestined for poor health.

(gentle music)

Hitler's ancestral Homeland was in lower Austria.

In this isolated region, inter marriage was common

between peasant farmers and their families.

Hitler's parents were second cousins.

So he came from a pool of genetic stock

that may have been weakened by centuries of inbreeding.

Certainly that may have played out

in his mother Klara's life.

Her first three children did not survive past infancy.

So there was great relief when on April the 20th, 1889,

newborn Adolf survived.

Klara doted on Adolf, and they formed a very close bond.

But as a boy, he was prone to violent outbursts

and considered a lazy child.

A teacher at Hitler's secondary school

was not impressed by the young student,

recalling him as willful and arrogant,

unwilling to listen to advice

and demanding his fellow pupils

give him their unqualified subservience.

(dramatic music)

- I think this was characteristic of Hitler

from a very early age

and it exemplified the fact

that he was totally self-centered,

totally obsessive, incapable of having any opinion

that disagreed with him.

And he simply reacted in kind.

- [Narrator] At home at all Adolf Hitler's father, Alois,

an alcoholic customs official, was abusive and violent.

He would explode into a rage and attack his son,

and at times, his wife, Klara.

Hitler learned to be silent through the beatings,

once telling his mother that he didn't say a word,

even though he was whipped 32 times.

- So if you look at the household Hitler grew up in,

it's really a classic model of a dysfunctional house.

First of all, he had a doting mother and secondly,

he had a distant, rigid and punitive father.

So you've got the same kind of scenario there

that you have with many serial killers.

They have an over bonded relationship with their mother

and a much more distant relationship with their father.

- [Narrator] On the 3rd of January, 1903,

Alois Hitler died of a heart attack over his morning pint,

when Hitler was just 14 years old,

Four years later, Hitler's mother Klara died

after a long and painful battle with breast cancer.

Hitler was shattered.

He'd idolized his mother

and struggled to cope with her death.

- His mother gets cancer when he's 17

and he's absolutely devastated.

Edward, the Jewish family doctor

said he'd never seen anyone as devastated at a funeral

as he saw Hitler there when his mother died.

- [Narrator] With both parents gone,

Hitler joined his childhood friend August Kubizek in Vienna.

Hitler's dream was to be an artist.

He applied to the Academy of Fine Arts,

but was rejected twice.

The knock backs devastated Hitler.

With very little money and living in a men's hostel,

Kubizek observed Hitler's mental health deteriorating.

He would choke over a catalog of hates,

railing against everyone who didn't understand him

or appreciate him.

He felt he was being persecuted and cheated.

His friend felt sure that Hitler was becoming unbalanced.

- He was certainly shattered when his mother died.

And I think he internalized this

into this just carrying on with this loose lifestyle

and somewhere, trying to think, what am I going to do?

'Cause I don't think he really had any idea.

He really was drifting.

(dramatic music)

- [Narrator] And it seems, Hitler's physical health

was about to be called into question too.

The First World War was about to change Europe

and the Austro-Hungarian army was calling for recruits.

When Hitler reported for his medical examination,

he was rejected as unfit for combat.

This might have been the first indication

that something was wrong.

- Military medical boards are notorious

for being pretty tough.

They're not interested in excuses.

And there certainly are cases where they've stamped people

with missing a leg as fit for combat duty.

Hitler was found unfit for duty and there was vague talk

or he gave vague talk that it was for respiratory reasons.

Now this is nonsense.

Hitler never had chest illness.

So my theory is the only other reason

they could have knocked him back

was they found the congenital defects,

and that's something they didn't want in the army.

- [Narrator] Apparently the standards in the German army

were not as high as in the Austro-Hungarian military

and Hitler was accepted there.

Adolf Hitler enjoyed being a soldier,

but his colleagues found him odd and peculiar.

- Hitler was a competent soldier.

He was a bit of a lone wolf.

We don't really know exactly

what his officers thought of him.

Occasionally in private conversations,

there's evidence that there was something about Hitler

that didn't endear himself to other people.

(gentle music)

- [Narrator] One account from a soldier in his regiment

claimed Hitler would suddenly jump up

and make loud speeches attacking Jews and Marxists.

They gave him the nickname, Crazy Adolf,

but something else made Hitler the topic of barracks gossip.

Hitler's close friend Ernst Hanfstaengl,

says that Hitler was the victim of sexual bullying.

Old army comrades who saw him in the washhouse

noted that his genitals were almost freakishly undeveloped.

- Well, there were always rumors

about this and it started with the fact

that when he was out say picnicking with these friends

and he'd go behind a tree to pee,

he could always see that he leaked afterwards.

Whenever a doctor examined him,

he would never let them take his shirt off

or examine his abdomen or pelvic area.

So that sort of set up the thought amongst people

who are looking at him, there's something wrong there.

(dramatic music)

- [Narrator] And it seems there was.

A Soviet pathologist examining Hitler's burnt remains

at the end of World War II

stated that one testicle couldn't be found.

(keys tapping)

This report was later challenged by some historians

as an attempt by the Russians

to portray Hitler as sexually deformed.

But it turns out they may have been telling the truth.

Recently discovered documents

from Hitler's time in Landsberg Prison,

after a failed attempt to overthrow the government,

point in the same direction.

Like the popular school boy song,

it seems Hitler did only have one ball.

- He went into Landsberg Prison

after the Bavarian Putsch, and like any prisoner,

he was examined by the prison doctor and the prison doctor

noted his weight, his height,

all the details, said he was pretty healthy and fit,

but he was missing the right testicle.

The likely explanation is that he had

what we call spina bifida occulta.

It is strongly associated with genital abnormalities.

So in Hitler's case,

he's got a missing testicle, it's called cryptorchidism.

So he had right cryptorchidism,

which is a congenital defect and he's got hypospadias,

and that is a hole at the tip end of your penis,

which makes you leak.

Hitler's secret was now out.

But of course it lay there almost like a non-smoking gun,

until discovery of the Landsberg records.

(dramatic music)

- [Narrator] Could such a deformity go some way

in explaining Hitler's brutal regime.

American psychoanalyst, Dr. Henry Murray believed so.

During the war, Murray was involved in a covert

US operation to understand Hitler's psychology.

He concluded that Hitler dealt with his insecurities

about his genitals by exhibiting brute strength,

ruthless domination

and military conquest in the world at large.

- This can have considerable effects on someone,

and certainly in Hitler's case,

he never was seen in a bathing costume.

He'd never let a doctor examine his abdomen

or take off his shirt.

And it's highly likely

it would affect his attitude to intimacy.

(gentle music)

- [Narrator] The contrast between Hitler

and the allied leaders could not have been more stark.

Winston Churchill loved swimming.

And despite Franklin D Roosevelt's severe disability,

he too was far less body conscious

than paranoid Adolf Hitler.

- But the biggest issue is in Hitler's racial attitudes.

As a member of the master Aryan race,

there was a strong bias against congenital problems

because that was carried by so-called others,

Jews, gypsies, thieves, homosexuals.

So this was a strong contradiction

to what he was putting out publicly

and must have led to a lot of ducking

and weaving on his part.

(whirring)

- [Narrator] Lance Corporal Hitler

was injured twice in combat,

at the Battle of the Somme in 1916,

when a shell exploded, wounding his left thigh.

And two years later, in a British mustard gas attack.

He was sent to a military hospital,

but while he was recovering, Germany surrendered.

Hitler was broken.

Later, he would write of that day with despair and anger

and ask whether it had all been in vain.

So a gang of wretched criminals

could lay hams on the father land.

- Hitler was shattered and this started his train of thought

that led to, what am I gonna do now that the war is over

and how do we get revenge for our unfair loss?

- I think Hitler believe that it had all been for nothing,

that Germany had been stabbed in the back

by those on the home front, the civilians, the Marxists,

the Jews that didn't understand what fighting

at the front was like, what that sacrifice meant.

And he aimed to put that right.

- [Narrator] His outrage at Germany's defeat,

along with his antisemitic, anti communist beliefs

found a home in the beer halls of Munich,

where far right members

of the German Workers Party Gathered.

(upbeat music)

- The Germans felt that they had lost a war.

They had lost economic power, prestige and territory.

They wanted greater economic strength,

not to be reliant upon American loans.

They wanted greater job security and they wanted

the prestige that they felt was owing to Germany.

- [Narrator] By 1921, Hitler was chairman

of the newly formed Nazi party,

a party that saw the German race as superior to all others.

It was a rapid rise to power and a demonstration

of Hitler's early commanding authority.

- Hitler became leader of the Nazi party

through the force of his personality.

I think Hitler was super charged by it.

It gave him a reason for being

that perhaps he hadn't had up until that point.

- [Narrator] By 1930, with Hitler as leader,

the Nazi party was the second largest

political party in Germany.

And Hitler's brilliant oratory skills

were drawing huge crowds.

He was called a born natural orator,

who began slowly and then all at once seemed to take fire,

as he railed against all the evils

he saw as the ruin of Germany, particularly the Jews.

(audience cheering)

Eyewitnesses commented on how in person,

away from the public stage,

he was a peculiarly insignificant and vacant figure.

Dorothy Thompson,

the head of the Berlin Bureau at the New York Post

was definitely not impressed when she met Hitler in 1931,

she called him formless, almost faceless.

He is the very prototype of the little man.

- Everything in public was the most crude way of saying,

I am powerful, I am big.

I am the ultimate weapon as a human being.

I think a good way of understanding it

is existentially, inside Hitler there was nothing,

he was only something when he projected out,

particularly with the speeches.

So take him away from that, and he just about collapsed.

- [Narrator] The Nazi propaganda machine

wasn't relying on Hitler's looks

and physical bearing to promote the Führer.

Instead, the Reich advanced Hitler

as a leader who worked tirelessly for his country,

clean living, healthy vegetarian,

who avoided all stimulants like alcohol, nicotine,

and coffee, but privately,

Hitler was suffering from a number of ailments.

- Firstly, Hitler was a complete hypochondriac,

there's no question about that.

When he became chancellor,

he developed all these minor problems,

skin rashes, bowel problems.

Remember, he was the great farter of history,

headaches, those sort of things.

A lot of this came from what you could call stress,

probably his diet, this kind of thing.

- [Narrator] No treatments seemed to give Hitler any relief,

but all that changed in 1936,

when he met Dr. Theodor Morell,

the man who had put Hitler on a path to certain destruction.

- Hitler and Morell for the first time

met in Munich in 1936,

they had a mutual friend, his name is Hoffmann.

He was Hitler's photographer.

Hitler told Morell that he has been suffering from pain

in his stomach, that his doctors couldn't cure him.

And then Morell offered and unorthodox way of treating him.

- [Narrator] According to Morell, Hitler's stomach issues

were caused by a complete exhaustion

of the intestinal system.

He prescribed a treatment of vitamins

and probiotics and Hitler immediately felt better.

That was the start of Hitler and Dr. Morell's relationship.

And it would last until a few days before Hitler's suicide

nine years later.

- Hitler now swears by Morell, he will not go anywhere,

do anything without Morell.

What Hitler didn't know is that Morell amidst other things,

gave him a yoga preparation with the organisms

taken from the bowel of a Bulgarian peasant.

If Hitler knew that, he would've gone crazy.

So this is the basis on which Morell

formed his relationship with Hitler.

Morell really was a quack.

- [Narrator] Dr. Morell became indispensable to Hitler.

And by 1937, he was appointed

one of Hitler's personal physicians.

Although he was the trained doctor,

hitler's generals were suspicious of Morell.

Hitler's main physician, Carl Brant,

feared Hitler was in danger of being poisoned

by Morell's prescribed cocktail of hormones and vitamins.

But Hitler wouldn't hear a word

against the man who was making him feel better.

He said he had the greatest confidence in Morell

and would follow his prescriptions to the letter.

- Morell gave Hitler these daily injections.

He slept late, he slept like till 11:00 AM.

It was normal for him to wake up,

roll up the sleeve of his pajamas

and get his first injection from Morell.

Then he thought, he's ready for the day.

These injections contained mostly vitamins

in the first four to five years of the treatments.

So an early, you could say

psychological dependency developed.

He thought, if Morell is close to me, I'm fine.

And this is actually how it was in the beginning.

- [Narrator] Hitler's inner circle

was unnerved by Morell's power over their leader.

General Heinz Guderian called Morell

a fat, unappetizing quack and Hermann G,

disparagingly referred to Morell

as the Reich syringe master.

(gentle music)

By 1943, with the tide of war turning against him,

Hitler's health was declining, as well as stomach cramps,

the Führer also suffered from headaches,

double vision, dizziness and tinnitus.

Hitler's secretary Traudl Junge, reported that Hitler

had become very dependent on Morell.

She claimed the doctor would turn up in person every day

to administer his usual medical working injection,

and these started to contain some very alarming substances.

- Morell was giving over 90 different medications,

about a dozen of them were heavy drugs.

Hitler's favorite drug was,

which is a euphoric making opioid that is on the market

still today as oxycodone.

It actually created the opioid crisis

in America and in other countries,

and Hitler was getting this oxycodone

intravenously in very high dosages.

So the effect was extremely strong.

It's a much stronger effect than your everyday junkie has

when he or she injects heroin for example.

(upbeat music)

- [Narrator] It's no wonder Hitlers unsalable faith

in his physician prevailed, but Dr. Morell

was testing dozens of unknown drugs on Hitler,

including extractions from the intestines

of male animals and amphetamines.

Hitler's girlfriend, Eva Braun,

also took advantage of Dr. Morell's endless supply of drugs.

Morell told Hitler's personal secretary, Christa,

he was giving him hormone injections from bulls testicles,

claiming, that should pep him up.

(dramatic music)

With so many drugs in his system,

Hitler's failing libido was obviously a problem.

Hitler's armament minister, Albert Speer,

questioned Dr. Morell's methods and influence on the Führer.

He commented that the injections had to be given

more and more frequently.

Hitler was under Dr. Morell's spell

and completely convinced of his personal physician's genius

and forbade any criticism of the man.

What Speer was describing was a classic relationship

between a junkie and his dealer.

- There's no doubt that throughout his time in office,

Hitler had bouts of great sickness, maybe of depression.

And so he became increasingly reliant upon Morell,

his advice and his drugs,

and it was a bit of a vicious circle.

- [Narrator] By 1943, Dr. Morell was giving the Führer

the addictive drug, as well as high grade cocaine,

injecting him several times a day.

It's incredible to realize that Hitler

was making decisions every day

that directly affected the lives

of tens of thousands of his own soldiers,

all while he was constantly high on drugs.

- Hitler became a human wreck

from 1943 on because all those medicines

that Morell gave him, late in the war,

started to show their side effects.

So he started trembling, his skin was yellow.

He was losing his train of thought.

He was not fit anymore at all.

- [Narrator] Did Morell turn Hitler into a drug addict,

or was he simply powerless to resist

the Führer's drug addled demands?

- British intelligence actually stop their plan

to assassinate Hitler.

They realize that actually Morell is doing their job.

Anyone high on drugs is not that much

in contact with reality.

And if you are the leader in the war,

you have to be very much in contact with reality.

You cannot live in a dream world.

This ultimately has to lead to terrible decisions.

So they were quite happy

with a degenerating Hitler still in power.

- [Narrator] Hitler began showing signs

of a serious medical condition.

His left hand would often shake.

Dr. Theodor Morell noticed this peculiarity

in 1941 and diagnosed it as a stress related condition.

- Hitler appeared perfectly healthy

to people around him and of course the German public,

but from 1942,

it became very obvious to people, to Goebbels,

to Guderian and other people have all listed comments

that suddenly, he's a very old man.

He looks overwhelmed, he shuffles, he drools.

He can't keep his arms still.

- [Narrator] His deteriorating health was a secret

Hitler could no longer hide.

He was suffering from Parkinson's disease,

a degenerative neurological disorder with no cure.

- Now what they were picking up was of course,

the escalation of his Parkinson's.

And that explains a couple of other things

about his behavior.

In the past, he'd always been meticulously neat.

As the Parkinson's went on, you could see he had food

sort of dripping down on the front of his shirt.

And it got to the stage that he couldn't sit down

in a chair, he needed pushed underneath him.

(gentle music)

- [Narrator] Did Hitler's Parkinson's disease

affect his decision making abilities

and influence the outcomes of the war?

Neurologists suggest as much,

questioning the reckless choices Hitler made

as his Parkinson's disease took hold.

- [Person] The Russian settled upon a strategy

that was to pay off handsomely for them, realizing.

- [Narrator] Like Hitler's steadfast refusal

to allow Paulus to surrender at Stalingrad,

in the face of overwhelming odds in January, 1943.

- [Person] Followed, blindly.

And so doing, stretched their supply lines

to the snapping point.

- [Narrator] Or his 1944 failure to defend Normandy,

or consider tactical retreats on the Eastern front,

condemning millions of his own troops to death.

It's also likely his worsening drug habit

left him unable to make clearheaded decisions.

- So Hitler really used very strong drugs

in regular intervals.

His drug intake became completely mad.

You could say because he was using cocaine,

which is a strong upper, and then getting oxycodone,

which as an opioid is always kind of a downer.

So he had this what in street language

is called speedball effect.

- By the 20th of July, 1944,

the tide of war had turned against Germany

and a plot to assassinate the dictator was underway.

At a meeting, inside Hitler's Wolf's Lair

headquarters in Poland, Nazi officer,

lieutenant Colonel Claus Von Stauffenberg

placed a briefcase with a bomb

underneath the conference table, close to the Führer.

When it exploded, the table leg protected Hitler

from the worst of the blast,

four people were killed and 13 injured.

Morell rushed to the scene of the bombing

to attend to Hitler and began removing splinters

of glass and wood from his body.

Hitler was scheduled to meet with Mussolini

later that evening

and convinced the doctor to give him something

to get him through.

His injuries would've been very painful,

but Morell dosed him up on one of the strongest opioids,

and Hitler was ready to meet the Italian leader.

- Well, Mussolini got out of the train at the Wolf's Lair,

was obviously informed

that there had been an assassination attempt.

Hitler was standing at the platform, high on the opioid.

So he didn't feel any pain.

And Mussolini said, this is a miracle.

You are superhuman.

You can already greet me and have meetings with me,

even though you've nearly been killed a few hours ago.

- We know that there were at least 42 assassination attempts

on Hitler between the 1930s and the end of the war.

Hitler knew about many of the assassination attempts.

The fact that he survived them reinforced his view

that he was sort of a Superman that had been chosen

to lead Germany in this struggle for survival

and that nothing could do him in

and that these merely confirmed his greatness.

- [Narrator] Hitler was very lucky

to survive this attempt on his life,

but his delusion that he was protected by some higher power,

along with his accelerating drug use, was taking its toll.

(dramatic music)

Hitler's capacity was failing on all fronts.

Germany was losing the war.

Over a month before the assassination attempt,

150,000 allied troops stormed the beaches of Normandy,

overwhelming the German army.

(gentle music)

Six months later, the Red Army

encountered their first horrific evidence

of the true nature of Nazi excesses,

when liberating Auschwitz concentration camp.

At the same time, the Americans launched Operation Cobra,

a surprise offensive and a key milestone

in the liberation of France and Germany.

Despite these heavy military losses,

Hitler was obsessed with seeking revenge

for the attempted assassination.

- [Person 2] Adolf Hitler, who had survived a bomb

planted by one of his own officers.

- [Narrator] In his paranoid state, he told his generals

that he would exterminate this nest of vipers

once and for all, and he did it.

It is estimated that almost 5,000 Germans were executed

after the July assassination attempt on Hitler's life.

The officers behind the plot

were hung with piano wire from meat hooks.

Their executions were filmed and later shown

to senior members of the Nazis and the armed forces.

at the Nazi military briefings

that followed this mass execution,

Hitler was chirpy and optimistic.

It appeared he still believed Germany would be victorious,

but it seems it may have been the regular injections

of opioids, methamphetamine, and cocaine

that were giving Hitler a delusional confidence

in the face of certain defeat.

- After the assassination attempt,

Hitler's drug use skyrocketed.

He used euphoric making opioids

every other day to boost his morale.

He used cocaine a lot, over 50 times

from early August till September, 1944.

So after the assassination attempt,

there's no more sober day for the so-called Führer.

- [Person 3] And a new ally

came to the aid of a Soviet forces.

- [Narrator] By the spring of 1945,

the Red Army was closing in on Berlin,

a gray haired 55 year old Hitler

moved into the Führer bunker in January.

And he insisted Morell come with him.

- The bunker was quite small actually.

The only people that had bedrooms in the bunker

were Hitler and Morell.

So their relationship was still very intimate,

but that changed over the course of those bunker months.

And this probably changed

because Morell didn't have the drugs anymore.

- [Narrator] The British had bombed the pharmaceutical plant

responsible for making, and it was getting harder

and harder to find the drugs Hitler craved.

By 1945, Hitler had no opiates,

no cocaine and no methamphetamine.

- There's a note in Morell's diary

where he writes that two of his helpers

are driving on motorcycles through bombed out Berlin

from pharmacy to pharmacy,

trying to find the drugs for Hitler,

but even the pharmacies didn't have drugs anymore.

- [Narrator] Hitler would've been sick

and suffering severe drug withdrawals.

- He had become a drug addict

and and didn't have the drugs anymore that he needed.

That was a very real physical problem,

which led to terrible withdrawal symptoms.

Hitler just degenerated

and became this raving sick guy who was just in pain

all the time and just not functioning at all anymore.

- [Narrator] A few days before Hitler died,

he told Morell to leave the bunker.

- One mistake a dealer should never make

is to make his client dependent on a substance

and suddenly not be able to supply the substance anymore.

Hitler fired Morell in late April, 1945.

He said to Morell, get out of the bunker,

I don't wanna see you anymore.

You've been turning me into an addict,

so Hitler seemed to have realized by then

what had been happening to him.

- [Narrator] On the 20th of April, Morell left the bunker,

taking one of the last planes

out of a completely destroyed Berlin.

The head of the German state was a spent force.

- And we can see in those weeks in the bunker

how he self destructs,

he becomes very aggressive against everyone around him.

And he also starts destroying himself

by becoming self abusive,

picking his own skin with tweezers.

He just becomes a very unhappy, unhealthy, horrible person.

Maybe that's the true Hitler that he always was.

Now it really comes out.

(sirens whirring)

- [Narrator] On the 28th of April, 1945,

Hitler married Eva Braun in the bunker.

Two days later, Eva took her own life

by swallowing a cyanide pill

and Hitler was right beside her.

He wanted to make sure he was successful in his own death.

He swallowed a cyanide capsule

and then shot himself in the head.

It was the final predictable act of a twisted mind.

- Hitler was the greatest narcissist in history.

Death comes as a part of every act that he plans.

I will kill people who get in my way

and I will eventually kill myself

to show the world what they've lost.

It's another indication of his absolute self-belief.

The world must come to me, otherwise I go.

(speaking in foreign language)

- [Narrator] 75 years after his death,

Hitler's health is still scrutinized.

Fragments of his chard body have been studied

and rest restarted by scientists

hopeful they might find a gateway

into understanding the destructive force of Hitler.

Pathologists, using pioneering profiling techniques

have tried to understand Hitler's intensity.

Geneticists have looked into Hitler's heritage

for clue to his perversity,

doctors have poured over Hitler's medical records.

Some shed light on his health,

but are not a window into his mind.

We may never have the tools to understand Hitler's evil,

but what Hitler does confirm

is that evil can exist in humankind.
