It's far too easy to hate Sasuke with what seems to us nothing but constant betrayal.
In truth, which even Naruto was able to see, all of Sasuke's actions are justified.
From turning the most powerful family into an outcast, where they forced them to live a life under watch, which created an underground mafia that wanted to get out of this style of life. Just to have one of their own (Itachi) killing them all, then finaly having Itachi killed by his own brother.
In other words, if you look at it in Sasuke point of view (which people who hate him should). He's watched his family get slaughtered infront of his face by his own loved brother, lived a life just to bring justice to his brother just to find out that all along his family were really treated like trash by Konaha (which he didn't get to witness due to his young age), and to find out AFTER killing his older brother who he loved that he was just following orders from Konaha for Their own peace (disregarding the Uchiha completely). Give me one good reason he should like Konaha? and give me one good reason how can he trust anyone or keep sane after all he's been through?.
You can still see he has feeling towards Naruto no matter how hard he tries to hide it, he always asks him "why do you care" and wants to hear what Narotu has to say as if he wants THE answer to save him from the misery he's going through.
Even though from when he left Konaha, Naruto wasn't exactly somethign big, he was a little trouble maker (he's not aware of Naruto's recent heroisim. Yet it's only Naruto Sasuke's willing to even give a second to listen to and ask questions to.
To hate Sasuke so blindlessly is tbh unfair and unjust, it's an indication of beign narrow minded and only looking at it from the leaf Point of view.
Pain has said it best, when he told Naruto "why is peace only used when it involves the big countries while the small villages like my own suffer for it as if it didn't matter?". Hasn't that made you think for a minute about wth... it sure has made Naruto think that way. Which makes me wonder what will naruto start feeling towards Konaha the more negative stories he hears about what they have done. (Uchiha clan and the story of Pain or of 2, and I'm sure theres more to come).
