In lieu of today's episode: the anime added a wonderful bit of Sasuke seeing all of Naruto's training and his determination to become Hokage changing from selfish to selfless. We can literally see Sasuke's Curse of Hatred dissipate when he realizes how alone he is and how many allies Naruto had made. But there's another layer:

Sasuke saw just how much effort and dedication Naruto poured into all of his training and goals...and then realized that Naruto's initial motivation was just to save him.

Sasuke seeing this was what caused him to finally come back. Seeing how dedicated he was to just one friend and how much he would sacrifice and fight through to save him, what would he do for the world? Maybe he saw that one person can bring about peace. He saw what Itachi did.
