If you want to read a very spooky research book that describes hitler's behavior in a way that is much like berg's get a hold of "The Psychopathic God Adolf Hitler" by Robert G.L. Waite published in New York by Basic books inc.
It is a very penetrating view of a meglomaniac's insanity and overall behavior that bears a striking resemblance to berg and his folly. Hitler also thought he was a messiah for his race and age. He felt Jesus saved the soul and it was, he, Adolf Hitler that would create and save a "proper" physical kingdom. The similarities of viewpoints between these two sociopaths is pretty creepy.
