I dont even remember why Sasuke is pissed with the kages. He wants some kind of revenge and seems that that's all it matters to him. But the shitty coward wants to kill them while inside the cocoon. Thats just plain execution. Even his clan had the chance to fight back.

For that matter he should use the godringan travel back in time and fight them when they are 2 years old. That would be pretty challenging, eh, mr hero?

Lets see where this goes but he should have his ass kicked by Lee, TenTen, Ino and Hinata.
