I'm surprised i never thought of this before but there was an animated series that i absolutely loved called 'Naoki Urasawa's Monster' which was about a Japanese brain surgeon who worked in Germany. He saved the life of a boy who was shot in the head. But it turned out that this boy was a sadistic murderer that used peoples fear to control them and make them murder people. The boy was the German government secret project of creating another better Hitler but the boy knew this and turned against them. It had brilliant twists and character development and if you do watch this you have to watch every episode otherwise the whole thing will not make sense especially the conclusion of the series.
