Communism isn't evil, it's the people doing evil that are evil. Evil doesn't exist without evil people to perpetrate it. The problem with everyone being equal is that nobody really wants to be equal. The guy pushing the communist ideals doesn't want to be the rubbish collecting guy instead of the politician, even if the income was the same.

I don't think communism is good, or viable, but if it could ever work the the way it should it would not be evil.
