The story of revenge....
1st it started with the older son of SO6P not being the leader and swore to get revenge and never came back.
Than same happened to madara so he ran off and planned revenge and never came back.
Than Oro didn't become the hokage and he ran away planning and failing to revenge but never came back.
And now sasuke who also ran off for revenge.
BUT this time I think sasuke will do something no one else in this list did....HE WILL RETURN TO KONOHA. And that is one of the main point to not hold a grudge too damn long and to forgive and forget. And that is why naruto is the prodigy ninja....he just won't bring peace he will end this cycle of revenge.
