One problem with taking baby Hitler is that it would change the timeline. If WWII never happened my parents would have never moved to Los Angeles and never met and I would not exist. How many other nerdfighters would not exist from changes in the timeline.
According to Douglas Adams's Hitchhiker Trilogy (of five book), you can't change history because time fits together like a jigsaw (puzzle). Also I saw a Twilight Zone episode where someone went back in time to kill baby Hitler, but the baby was replaced by a baby taken from gypsies who became the true Evil Hitler.
Hm, the fact that the new baby became evil indicates that it is the environment in which the baby grows up that makes it evil. Although I guess it could be possible that it was the gypsy baby that was born evil, and if the real baby had been left there it would not have been evil. There are too many variables...
I think that the point of that Twilight Zone episode is : "You can't change history!" It seems if you try to change history, you then become part of the history that you were trying to change but couldn't.

I think that the only true way to test if evil babies are born evil or raised to be evil would be if we had a parallel universe, and left the original Hitler baby in one and replaced it in the other (or some other baby who became evil). If they both grow up evil, it would be their environment. If only one is evil, then it is the baby.
That would be a tad difficult to test...
