In the fanfiction, Naruto could hate his family if they were involved in something that went against his principles. For example, if they were part of a group that caused harm to others. Regarding Konoha, Naruto might have discovered some dark secrets about the village. Maybe Konoha had a hand in some past tragedies that affected him personally. And if the village always put him in dangerous situations without proper support, it could make him resent the place.
One possible reason could be a misunderstanding within the family. Maybe there were secrets kept from him that made him feel betrayed. As for Konoha, perhaps he felt ostracized or not fully accepted by the village despite his efforts, which led to his hatred.
One possible reason could be the lack of presence of his parents. Growing up without them, he might feel abandoned. And as for Konoha, if he hates it, it could be due to the way he was treated as an outcast, despite being the son of important figures. Maybe the villagers' coldness towards him made him resent the village that didn't seem to protect him from that.
One possible reason could be that he feels neglected. Maybe his family was always too busy with other things and didn't give him enough attention. This lack of attention during his formative years could have led to feelings of resentment.
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.
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 feeling neglected. Maybe his family was always preoccupied with other matters, like protecting the village, and didn't give him enough attention. So he grew to resent them.
It could also be due to some external influence. Perhaps an enemy manipulated Naruto's mind in the fanfiction, making him see his family in a negative light. This enemy might have used some form of mind - control or false memories to turn Naruto against his family.
One possible reason could be a misunderstanding. Maybe his team made a decision without consulting him, which made him feel left out and thus led to hatred. For example, if they took on a mission without him, Naruto, who values being part of the team, might feel betrayed.
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 a divergence in values. Maybe in this fanfiction, Naruto's family holds values that are completely opposite to what Naruto believes in. For example, if his family is shown to be more focused on power and status within the Justice League world, while Naruto values friendship and helping the weak.
