TBH, Hashirama also defeated Madara (the first time) and they became buddies again and build Konoha, similar to how Sasuke came back after VOTE2. Yet Madara went mad again and betrayed Hashirama, and ended up getting "killed". So at least according to history, another Sasuke EMO phase isn't unlikely at all. But this is a New Generation story, so i really doubt that Sasuke will become a main villain again.

Also, if i recall correctly, Asura said that if Indra will reicarnate to bring evil, so will his soul, in order to stop him. But if Indra's soul is at peace and cured from hatred, i doubt they will reicarnate again after Naruto and Sasuke.
