I was thinking if Sasuke helped defeat Madara ect... Would they still accept him back in the Leaf?
I think Kishi purposely didn't have him kill anyone because he had always planned for him to go back to the good side and the Leaf.
What do you think?
Also,
How does Shisui Uchiha have the Mangekyo Sharingan? Was he somehow born with it?
I don't see how he could, When he attacked the Kage summit, Temari stated that Sasuke has no future since he's now seen as a international criminal plus he wounded the Raikage and killed some of the Samurais plus was aiding Akatsuki by giving them a portion of Bee's chakra which allowed the Juubi be created. Plus Shikamaru, Kiba, and Shino all told Sasuke he can't become Hokage; no one trust him. Even Sakura doesn't, when Sai asked her she said she did but had a twisted face and Sai said he can see through her fake smile.
