Look im just saying that the only option it's obvious he wont surrender so either he puts aside his pacifist teaching and kill the greatest threat ever he has slaughtered to much to be spared! Thats what I hope Zuko teaches Aang they both can learn something from eachother
Aang needs gutts to give a few insluts to people and get the gutts to kill Ozai.
Zuko needs to lighten up and have the courage to stand up to his fahter.
