Children are the Devil
In anime Monster the main villain managed to manipulate a orphanage(kids and adults) into killing each other. He himself was just a kid back then. This villain was compared to hitller at some point and if I remember right even called the antichrist. of course that may be an exaggeration. Still it is interesting how much evil can a seemingly innocent child make.
I wonder how many of the dictators, grew up torturing animals.
