Why go after Stalin and let Hitler off when neither of them had done anything at that point, I mean it's not like Stalin was destined to become a horrible Dictator, the man intended to be a monk originally for goodness sake.
With the risk of going beyond and beyond the normal Devil's Advocate perspective, as far as I know, Hitler got rejected from art school, and, Stalin left the seminary on his own, I think. (Shucks, Stalin got into the seminary on a scholarship.)
