Sasuke would've also changed the world if the series hadn't been retconned. :/ Naruto is realistically useless when it comes to peace. You can not crush a corrupt system with pep talks and apologism.
Well, Naruto's good at breaking promises. What do you expect? I agree when people say that if it were Hunger Games, Naruto would be the defender of the Capitol.
Dumb dumb dumb Nagato for relying on the wrong person.
Naruto did that too, that's not something what Obito done, he chose death for saving others, that's different. Well, maybe, Sasuke is redeemable, but how he went in the story - his ending totally nullified all his bad deeds and ignored personal purposes as he got treatment on the same terms as Naruto wich is devalued Naruto's deeds in whole story in general.
I'm not saying Sasuke is redeemable. I'm saying that Obito didn't try to make amends more than Sasuke. Obito didn't choose death for saving others. He was going to die because he got his Juubi taken out.
