i think a couple of people already summed it up quite well but ya....Naruto was always alone. Sasuke was always alone too after his family was killed. He was everything Naruto wanted to be, acknowledged, naturally talented and attractive, Sakura liked him too at first...when they were put on a team together, Naruto actually had people to be around and form bonds with...his with Sakura and Kakashi is much healthier but its refreshing to see Naruto's dedication to his friends. He would do anything for Sakura and for probably any of the other konoha 9 and well Sasuke....obviously Naruto isnt giving up on bringing him back. Naruto does want to put an end to hatred and hes convinced he will be the one to do it and he will be the one to do it. We need more people in the world like him actually...i mean friends ditch each other all the time over stupid stuff (you guys know what i mean hopefully, i dont feel like going into too much detail) and you hardly ever see someone make a decision that doesnt involve some sort of retaliation. I think Sasuke has already changed a little and hes going to help Naruto fight Madara.
