Azula

The finale of Avatar had major Azula character development (i.e. faults). Azula was always sort of the perfect villain, she was in the same league as Voldemort and the Volturi: seemingly unbeatable. But the final episode showed her stupidity and it really made me feel bad for her. Not quite as much as, say, Ari or Zuko since she didn't have that "I just wanted to be loved" thing going for her, but still. She grew up in such a dysfunctional family, what with her mother gone and her father evil incarnate. It's just sad that she, rightly, had no faith in those around her. Obviously this was because she had no reason to trust them, she developed absolutely no personal relationships whatsoever. It was the same with the The Beach, she was incredibly unpopular at the local party merely because she had no experience trying to be liked. She was constantly blocking out every sign of the necessity of love so that she would be able to gain the power she so desired. She found that being feared was much easier than being loved, which is really, really sad since that never works out well.

Also, I read Death Be Not Proud, and Johnny Gunther, to me, is exactly who Edward would have been as a human (if he had an incurable brain tumor (and no I didn't just ruin the story if you haven't read it, you know that from the beginning)) which is cool... exept for the dying part *tear*.
