Anonymous2: this is so so sad.....in my heart I wish azule is imprisioned, but in a better place than we saw her father..... azula was mentally ill, she is not a criminal, she need help, and to be healed and cared, prison would never fix her, I think aang (as the avatar, and the moral responsability that carries with) would never allow zuko to imprision her like that
Anonymous4: @Anon2: Azula went crazy because she wouldn't trust anyone she couldn't control through fear. Therefore, anything bad that happened to her (including her decline into insanity) was self-induced or otherwise well-deserved.
TL;DR-Azula was crazy because she was a bitch.
