Because mao and Stalin didn't kill a billion people, that's just CIA propaganda.

But king leopard or whatever his name was, (correct me if that's not who that is)and Winston Churchill, and the Japanese emperor, they were all worse than Hitler no argument.

And I don't know who the last one is but he looks like a Turk so I'm guessing he was an ottoman?

In which case the history books actually do paint him as evil already (for depending themselves against British imperialism)
