Absolutely not. If she didn't go crazy, Zuko wouldn't become firelord and i'd be stuck up here in the northern water tribe sucking on lemons instead of macking on his face like i've always dreamt of.
I think Azula losing her mind had to happen. Now people know that she had her own termoil, and now she has a chance of being helped, and one step closer to eventually gaining happiness.
I do think otherwise, she would have been a pretty good ruler. Although, she was taught to Zeigen little mercy and all of these negative things. Her ruling could have put herself and her country in a really dark state.
