Avatar: The Last Airbender / The Legend of Korra - You maybe consider you could learn something from them?

well Sozin wanted to share the all the greatness of the fire nation with the rest of the world so i guess Ozai wanted to achieve what his grandfather never could.

What Korra can learn from Ozai is not to be an asshole and not to mentally and physically abuse her kids.
Granted Zuko turned out alright all things considered, Azula on the other hand… not so much.
