GameDynamo - "There's a wide array of reasons why one might find a villain to be affable. Perhaps they're laughably incompetent and can't seem to effectively commit a crime no matter how hard they try. Maybe they're simply so charismatic that one can't help but be drawn to them. It's possible that they display a degree of honor, friendliness, or deferral to the heroes (or that they're outright cheerful).
Whatever the reason, all the villains on this list are bad, and that's good: we love them for it. "
