Another possibility is that he has found a new purpose or a new community outside of Konoha. He could have met new friends or allies who have shown him a different way of life. This new life might be more appealing to him than going back to the structured and sometimes restrictive environment of Konoha.
One reason could be that he feels betrayed. Maybe there were some political decisions in Konoha that made him feel like he was being used rather than truly valued as a ninja. For example, if he found out that some of the higher - ups were only interested in his power as the Jinchuriki of the Nine - Tails and not in him as a person.
However, it could also force Konoha to reevaluate its treatment of its ninjas. Maybe they would realize that they need to be more inclusive and less self - serving in their actions. This could lead to some positive changes in the long run, such as better treatment of Jinchurikis and other marginalized ninja groups.
It could also be related to the way Konoha has dealt with other issues like the Uchiha clan massacre. If Naruto discovers some aspects of Konoha's involvement in it that he finds morally unacceptable, such as covering up the truth or being complicit in some way. This could make him lose faith in Konoha and be unable to forgive it.
One possible reason could be fear. Naruto has the Nine - Tails within him, and some in Konoha might be too afraid of its power getting out of control. They may not fully trust Naruto to keep it in check.
One reason could be betrayal. If Naruto discovers that some in Konoha have been secretly plotting against him or have been involved in something immoral that goes against his values, he might forsake the village. For example, if there was a conspiracy to keep him from achieving his true potential for their own gains.
One possible reason could be fear. Naruto is extremely powerful, and some in Konoha might fear that he could one day lose control of his power. Another reason could be political intrigue. There may be certain factions within Konoha that see Naruto as a threat to their power and influence. Also, jealousy might play a part. Naruto has achieved so much and has the love of many, and some might be jealous and thus plot against him.
Perhaps the Konoha leadership made a bad decision. They might have thought that distancing themselves from Naruto would be better for the village's overall image. Or they were influenced by some elders who held grudges against Naruto's father and took it out on Naruto.
One possible reason could be that Naruto discovers some dark secrets within Konoha. Maybe he finds out that the village elders have been using him all along, not truly caring about his well - being but only his power as a Jinchuriki. This realization could be so shocking that he decides to turn against the village.
One possible reason could be that Naruto discovers some dark secrets about the village leadership that go against his values. For example, if he finds out that they have been using underhanded means to maintain power.
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.
