"I don’t think I could play an entire game that way without deciding to have the hero undergo a redemption arc, but I’ll try it for EA."
That's my problem with giving evil "a try". It just never works for me.
You could try starting as an ordinary person, one who tried to do evil in the world, but then gradually, through weakness, falls into good habits, becoming increasingly Good, though he struggles against it. Then, near his lowest moment, he sees the darkness, and remembers his true self. He turns, fights against Good and eventually triumphs in Glorious Evil. At the end he looks back on his life, and he has a quiet satisfaction of having done the Evil thing. In the background though, not far away, is the ominous calling of Good again...
