One possible plot could be Naruto finding a way to overcome the hatred of the villagers through his own strength and determination. Maybe he starts to show his true power and gradually makes the villagers realize their wrongdoings.
The fanfiction could explore the backstory of why the villagers torture Naruto. It could be that some evil influence, like a hidden group within the village or a curse, is making them act this way. Naruto, being the strong - willed person he is, might try to uncover this mystery. He would use his detective skills, similar to when he solved various missions. As he gets closer to the truth, the torture might intensify. But Naruto's resolve would not break. He could also find unexpected allies, perhaps some of the older ninja who remember a time before the village turned against Naruto, and they would help him fight against the forces that are causing this unjust treatment.
Naruto would be confused. He's grown up believing that the village is his home and the villagers are his family, at least in a sense. So when they start torturing him, he can't understand why. This confusion would mix with his pain and anger. He might also feel a sense of loneliness that is deeper than anything he's ever felt before. Even though he has friends like Iruka - sensei, the fact that the villagers as a whole are against him would make him feel isolated. However, his inner hope and the belief that things can change would keep him from completely breaking down.
Naruto could develop into a more vengeful character at first. The continuous torture by the villagers might make him angry and want to get back at them. But as the story progresses, he might realize that revenge is not the answer and instead focus on making the village a better place for everyone, including himself.
One possible reason could be fear. Naruto has the Nine - Tails inside him, and the villagers might be so afraid of the power of the Nine - Tails getting out of control that they decide to take extreme measures. They might see Naruto not as a person but as a potential threat that needs to be eliminated.
One possible reason could be the way the villagers treated him as a child. They ostracized him because he was the host of the Nine - Tails. He was often alone and looked at with fear and disdain, which could have gradually built up his hatred.
One reason could be years of built - up resentment. The villagers have treated Naruto poorly for so long, constantly shunning him and making him feel like an outcast. In fanfiction, this could reach a boiling point where he just snaps. For example, if someone in the village made a particularly cruel comment about his parents, it might be the last straw.
It could also be a situation where Naruto is framed for a crime he didn't commit by someone in the village. As a result, the villagers turn on him even more, and in his self - defense and anger, he ends up fighting back and killing some of them.
Naruto would probably start by recruiting his friends and their families. He knows them well and trusts them, and they share his values. He could also offer a new start to people who have been ostracized from other villages. His reputation as a hero would attract many who are looking for a better place to live.
Naruto might react with confusion at first. He has always wanted to be accepted by the villagers, so being attacked is the opposite of what he expected.
