Another reason could be that he witnesses corruption or unfairness within the village leadership. If he sees that the system is rigged against certain groups, including himself or his friends, he could grow to hate Konoha and decide to leave.
Perhaps she discovers some dark secrets about Konoha's past. Things like the way the village treated certain clans or individuals unfairly. If she uncovers that Konoha was involved in some unethical actions in the past, it could make her lose faith in and start to hate the village. Also, if her loved ones were wrongly treated or sacrificed by Konoha's decisions, that would be a strong reason.
Perhaps he discovered some dark secrets about Konoha that made him lose faith in the village. For example, if he found out that the village leaders were involved in unethical or immoral activities that were against his values, it could make him hate Konoha.

One possible reason could be that Naruto discovers some dark secrets about Konoha that shatter his idealized view of the village. Maybe he finds out that the village elders were involved in unethical practices, like using shinobi for immoral experiments. This would make him lose faith in Konoha and decide to leave.
It could also be due to a lack of support. Naruto was constantly in trouble and trying to prove himself. If his family didn't show up in any way to support him and Konoha didn't do enough to encourage him in a positive way, but rather just punished him for his pranks, he might grow to hate them both.
One possible reason could be that it goes against the original essence of Naruto's relationship with Konoha. Naruto has a strong bond with Konoha, and yaoi fanfiction might distort that relationship in a way he wouldn't like. Another reason could be that Naruto is a character who values traditional values and friendship in a non - sexualized way, and yaoi fanfiction often sexualizes male - male relationships which he may find inappropriate.
Perhaps Naruto discovers some dark secrets about Konoha that go against his values. Like if the village has been involved in unethical practices that he can't overlook. This could be things like using underhanded tactics against other villages, which would make Naruto, with his strong sense of justice, turn against Konoha.
One possible reason could be a sense of betrayal. Maybe he felt abandoned or mistreated by Konoha in some way. For example, if he was shunned because of the power within him that others feared.
One possible reason could be to seek stronger opponents outside of Konoha. Naruto might feel that he has outgrown the training opportunities in the village and wants to face greater challenges.
One possible reason could be that the villagers never fully accepted him despite his efforts to protect Konoha. They might have continued to treat him as an outcast, which could have led to his growing resentment and ultimately his banishment if the situation got out of hand. For example, if he was wrongly accused of a serious crime and instead of getting a fair trial, the village elders decided to banish him.
It could also be due to differences in values. If Dark Naruto had different beliefs about power, friendship, or loyalty compared to his family, and they constantly clashed over these, it might lead to his hatred. For instance, if his family adhered strictly to Konoha's traditional values but he saw them as restrictive.
