Bin Laden without reference to his religious beliefs.

This was a guy who, when he was a teenager,

was praying seven times a day, fasting twice a week.

On the other hand, he was also a mass murderer.

What was his relationship to religion?

[music playing]

Given how religious Bin Laden saw himself,

it's not a surprise there's a lot of religious material

on these drives.

How great is our last panel, [inaudible]..

[non-english singing]

MAN: He would often recite verses

from the Quran in his letters.

He would refer to sayings of the prophet Muhammad

in his speeches.

He thinks he's religious.

He thinks he was doing the right thing.

But he was not a religious authority.

He was not a graduate of a seminary

or any kind of traditional religious training.

And so we have someone who's a non-specialist making

unorthodox interpretations of the faith,

because he actually starts by acknowledging that Islam

prohibits the killing of noncombatants in warfare,

but then goes on to explain, in his mind,

why the political situation that we are living in

allows him to violate that rule.

What he did was to use political justifications

to violate a religious edict.

MAN: This homemade video found on the hard drives

begins, as many of these al-Qaeda videos do,

by quoting a religious verse with chanting in tandem,

and then the message becomes clearer.

We hit the United States, and we scared them.

Then inevitably, Bin Laden himself speaks,

preaching to his followers.

And I think it's a really telling piece of propaganda,

how it weaves together religious imagery

to superimpose them on the tactics

and actions of al-Qaeda.

This homemade propaganda was crude.

But tragically, it was also effective.

He was using religion as a tool.

[non-english singing]

It's a means to control people, to make people do

whatever you want them to do.

And the ends justify the means, like any psychopath

can justify anything.

I mean, at one point, he actually told his commanders,

don't shy away from shedding blood.

You know, if you look at the crusade,

do you think Christianity is a crusade?

No.

The same thing-- it's people using religion

to obtain political goals.

I think it's tragic that we let

a criminal define the religion of 1.8 billion people.

We would never take the word of the KKK to define Christianity.

It would be ludicrous.

It would be offensive.

If the Quran is a recipe book and it

called for a tablespoon of sugar in the recipe,

and extremists would read that and put a cup of sugar

instead--

so taking what the Quran says and taking it to its extreme.

Bin Laden didn't do that.

He read in the Quran, you need a tablespoon of sugar.

And instead, he put a cup of cyanide.

That's not an extremist.

That's a deviant revisionist.

Bin Laden's view of his religion and violence

extended to his own family.

Terrorism was the family calling,

and he was willing to sacrifice even those closest to him

for his self-styled holy war.
