Everyone starts off as children. To quote the Fourth Doctor in Doctor Who, “..If someone who knew the future pointed out a child to you and told you that that child would grow up totally evil, to be a ruthless dictator who would destroy millions of lives, could you then kill that child?”. In this case, that quote would apply to the children who would later on become one of the most evil people in history. From dictators, to serial killers, the most evil men in history all started out pure and innocent, and didn’t know any better. Well, the latter one certainly applies to them even when they grew up.
