Oh! At this point... I really don't know. I guess it just depends on how it goes. If Ozai pretty much completely destroys the Fire Nation while Azula is in prison/wherever she goes after getting out, then she'll probably... snap a little, and won't be in good enough shape to fight him. DX But if he doesn't completely destroy everything and she sees the situation as salvageable, then it depends on what he's doing at the time. She won't want to weaken the Fire Nation by starting a civil war while they're still trying to win the global war, but she'll do it if she thinks Ozai is still on the warpath to destroy absolutely everything.
