Well, one possibility could be that Naruto discovers that his friends have been secretly working against him in some way, like lying about their intentions or using him for their own gains. Maybe they've been making deals behind his back that go against what he believes in.
In such a fanfiction, Naruto might leave his village in anger and sadness. He could go on a journey of self - discovery, trying to come to terms with the betrayal. Maybe he'd meet new allies who help him grow stronger and more independent.
One possible plot could be that Naruto discovers that his friends have been keeping secrets from him that make him feel betrayed. For example, they might have made a deal with the village elders that goes against Naruto's values. This would break his heart as he thought they were all in it together.

Perhaps in this fanfiction, Naruto discovers some dark secrets about the village. Secrets that make him feel like he's been used all along. Like the village was only using him as a weapon against their enemies. This realization could make him resent everyone in the village, thus hating everyone.
Well, one possibility is that Naruto is framed for a serious crime he didn't commit. Maybe someone fakes evidence that he's been working with the enemies of the village.

The plot could be that Naruto discovers a dark secret about his family that makes everyone in the village fear and reject him.

He might find allies in unexpected places, like some of the outcast ninja from other villages.
Ino could be a very complex character in this fanfiction. It's possible that she cheats on Naruto because she has a fear of commitment. Naruto is a very passionate and all - in kind of person, and that might scare Ino. So, to avoid getting too deep into the relationship, she cheats. Or perhaps there's a power struggle at play. She might think that being with a different person would give her more influence or status in the ninja world. And there could be a hidden agenda that she's following, something that she can't achieve with Naruto but believes she can with someone else.
In the long run, Naruto might try to find a way to redeem those who cheated on him. Despite the pain, his kind heart would still hope for the best.

Maybe he's been influenced by a powerful dark force or a powerful enemy has tricked him into believing that everyone is a threat to the world he wants to protect. So, he decides to take extreme measures and kill everyone to 'create peace' in his warped sense.
