I think you always learn something in every character you play onstage, either personally or creatively.
People are fascinated by evil because its mysterious and it doesnt seem to have a rationale behind it, and the second you say that Hannibal Lector was abducted as a child and he had to eat his sister or something like that, it becomes immediately mundane. The character becomes mundane.
I've auditioned for normal characters. But I never get cast.
If you want to do your version, go off and write it. You bring your knowledge to it, and you can use that to shape it and color it, but it's someone else's version of that character. You're not actually playing the real person.
