Kakashi grew as the son of the famous konoha white fang who committed suicide cos he put the mission first before his team. they died and the village slated him for it.
He had to be alone and hated himself until he met rin. He found love and then a misfortune hit him yet again.. He killed rin, accidentally.
He had to live with the guilt. As a sad loner, he trained and grew up to be a badass. he was chosen to lead team 7, maybe that would make him happy. Happiness finally came and Sasuke decided to go rogue. He couldn& #39;t stop him.
Sasuke had his revenge on Danzo and he had to be named hokage cos he& #39;s the most elite ninja alive. His name was written and sculpture inscribed as the 6th hokage of konoha.
