I think it's because people HATE the idea that he was a normal man, with a normal life, just like everyone else before the war. People much prefer to think of him as some mythical monster instead of accept that regular people can be that evil
well, a bomb went off in a room with him and several other people in it and then HE ATTENDED THEIR FUNERALS! THE BOMB DID NOTHING TO HIM! maybe he was a monster?
Wait, I don't have to be?
