Characters are, quite obviously, something very near and dear to my heart.
Villains are always an amazingly fun thing to experiment with.

Perhaps my favorite kind of baddie is the sort that isn’t, really, bad.  Or, rather, their badness has stemmed from something that is, at its core, good–it’s just been taken to such an extreme that it is no longer good.
A prime example of this is Javert in Victor Hugo’s Les Misérables; really, he just wants justice.  It is this hatred of forgiveness that is his demise….  But I feel that it makes for such an interesting character–a baddie that you can identify with more than others, perhaps. 

Do you have a favorite villain?  Who is it and why?
