After listening to the Hokage, I think the only change Sasuke make, is going full evil l(I would) and it won't just be about revenge on the leaf but ruling the world. I mean the coversation so far have change nothing, the Hokage are confirming that the leaf treated the Uchiha like dogs and Senju clan did hate them and never was going to let a Uchiha become Hokage, than village used the only Uchiha that had a chance to become Hokage to kill his clan and family(other than Sasuke) and betrade Itachi as a trader(instead of Hero) to the village. Which interm made Sasuke Hate him(his brother who love him more than anything) and set him up to fight Itachi to the death.
To me if Kishi have Sasuke go good guy " let me help you Naruto and the leaf defeat the only Uchiha who knew this village come together thing was bogus" would be total crap. I think now this give the reasons for Sasuke to now want to kill Naruto, with no I might have some love for you like a brother talk jutsu, but instead fight at full power intent to kill mind state and get him on some Orachmaru power hungry cold blooded do anything to become the best all time villian(which would be great for a Naruto vs Sasuke part 2).
