I find that when a villainous or evil character -- especially serial killers, like in [i]Dexter[/i] -- acknowledge that they are evil it adds another level of depth because it shows that they are capable of at least understanding, if not feeling, human emotion and behavior to a point that they can analyze themselves and realize that by the majority's standards they are in the moral wrong. It makes them much more fascinating and interesting than transparent two-dimensional characters. I think Clyde may not necessarily be villainous because he likes it, but because he simply does it. He may or may not even like it, but he does it either way. And, of course, thank you for the feedback!
