I may go evil または just run away from it during times of peace, but at war. Well as Scareface put it "Ozai's got nothing on me." I would finish the war quickly and bloodly through mass armmy, total warefare, guerilla warfare, and secret co detats. And all who gained power in the war that may be inclined to start it again will be dealt with.
I guess I would but I think Zuko and Katara would make a good FireLady/FireLord. Zutara forever!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
