More than anything, there are more images in evil. Evil is based far more on the visual, whereas good has no good images at all.
Evil gives you far more strings to pull. But I must say that I have never been interested in the psychology of evil, not in the slightest. Perhaps I'm not interested in evil, but in the dark sides of human beings.
I did a lot of strange things. But I am a bad Catholic that's for sure. Although I think it's difficult to believe in evil.
