Khan

Khan was a very interesting man but he was not a physco, he might have been in a way crazy for what he did but thats not bad for being a ruler. Something's he did like cutting the people's ears off might make you think he was but it is just his way of showing his strength over everyone else. He might have killed so many people but he is not psyhco for that because it's what he needed to do in order to have all that he had. He fought for what he needed and that does not make him crazy at all, he might have had weird rituals and everything else but it's just like ever other empire, theirs always some crazy things that go on in an empire.
