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.
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. He might also feel betrayed if his so - called friends turned their backs on him for some reason.
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 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.
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.
One possible reason could be feeling betrayed by the village leaders. Maybe they made decisions that Naruto strongly disagreed with, like how they treated certain groups or individuals. If Naruto felt that Konoha was no longer the place that stood for justice and fairness as he once believed, he might abandon it.
One possible reason could be that Naruto discovers some long - hidden secrets about Minato that he feels betrayed by. For example, if he found out Minato had made a deal that affected Naruto's life negatively in some way, like with the Kyuubi. Maybe Naruto feels that Minato sacrificed him for the greater good of the village without really considering his future or feelings.
Perhaps in this fanfiction, Naruto has been influenced by some external force. It could be a dark entity that has corrupted his view of Team 7. He might see them as a hindrance to achieving some greater, more self - centered objective. Also, it could be that Naruto has had some sort of personal revelation about his past and blames Team 7, or certain members of it, for things that he now believes held him back in the past.
One possible reason could be a misinterpretation of Kushina's actions. Maybe some events were presented in a way that made Naruto think she was neglectful or had made bad decisions in the past.
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.
Another reason might be that Naruto is seeking a greater purpose. In the fanfiction, his 'godlike' state could make him realize that there are threats out there that he can't face while being tied to Konoha. He may leave to protect the world on a larger scale, believing that he can be more effective away from the village.
