And yes, taunting someone about their potential death is fucked up. Azula is one intensely fucked up individual and anyone who says anything ever remotely to the contrary is a fucking retard. But she's also not irredeemable; the comics, at least, have shown that she understands she's fucked up but tries to push it down and deny it to maintain some small grasp on sanity. She has the potential to get better.
That alone is proof Azula isn't evil. Evil doesn't care what mommy thinks, or what big brother thinks. Evil doesn't wrestle with doubts about whether or not it's doing the right thing. Evil doesn't break down in years when it realizes its fears may have been validated.
Azula isn't evil. She's fucking crazy and needs intense psychiatric help and heavy doses of antidepressants, but she's not evil.
