I would judge fascism to be an evil worldview because it usually involves the idea that one ethnicity or nationality is intrinsically better than the others. I would not judge communism to be an evil worldview because at bottom, its core principles and motivations are good, and in theory, I think it could bring about a lot more happiness than our current capitalist system. I would consider the millions killed or left to starve in the name of communism to be victims of human imperfection rather than communism itself - the result of us not setting up a communist system properly. I would also concede that, the human condition being what it is, it may not be possible to make communism work.
