Number 3
3. Naruto, Sasuke
He wouldn't think about it, think about all the ones he left back at his home. No, he had no home anymore.
He left it all behind, for power, to kill his brother. The last member of his family and the one who had massacred the other members of his clan.
He would forget about everything, because to remember would mean to regret. And he wouldn't regret.
He's standing on his own, learning how to live his life for himself. He would gain power, he would defeat his brother. And prove to Naruto that he was stronger.
