Who is the most evil man in history?

"Evil" is broadly defined, but in terms of people killed, Genghis Khan killed about 10 percent of the world's population. Nobody else has come close to that.

Mao killed at least 60 million people and communism is still killing in China and elsewhere.

Dang - Is that true?
If so, he was a busy dude.
Must have had great organizational and leadership skills.
