Re: What would it take to make Sasuke come back to Konoha?
Sasuke will never, NEVER return to Konoha. I could spend an hour listing al the reasons why not, but I'm lazy, so I'll pick one good one: Sasuke is a criminal. He became a criminal when he left the village to conspire with the Konoha's greatest enemy. And if he did come back, he'd be thrown in prison for the rest of his life. It would be unfair for Tsunade to just forgive him and let him live normally like he did before leaving. So unless you count being a lifer in Konoha's prison as returning to the village (I don't), there is not even a remote chance that he will return. And it's more likely that he'll die.
