Another possibility is a mind - control or false - memory scenario. What if an enemy implants false memories in Naruto's mind, making him believe that his family abandoned him on purpose and that Konoha has always been plotting against him? This would cause him to hate them until he discovers the truth. However, this hatred would drive him to seek revenge and might lead to a very different Naruto than we know from the original series.
In a fanfiction, Naruto might hate Konoha and his family if he has been constantly ostracized and treated unfairly. Despite his efforts to protect the village, if the villagers continue to shun him and his family doesn't step in to support him properly, he could grow to resent them. He might feel that Konoha is a place full of hypocrisy, where people only pretend to care about him when they need his power.
One way to justify it could be through a series of betrayals. Maybe Naruto discovers that Konoha has been using him all along, and his family has some dark secrets that make him feel betrayed. For example, if he finds out that his father was involved in some unethical experiments that led to the suffering of many villagers, that could turn him against both Konoha and his family.
In the original Naruto story, Naruto loves his village and eventually comes to understand and accept his family. But in this fanfiction, the hatred is a complete contrast. It changes the whole dynamic of Naruto's character and his relationships.
A potential plot twist could be that Naruto's hatred is actually a cover - up for his love. He might be pretending to hate Konoha and his family to protect them from a greater threat. Maybe there's an enemy who would target them if Naruto showed any affection, so he creates this false front of hatred.
Another way is through his attitude towards the villagers. He would show no respect or kindness to them. Instead, he would be cold and hostile, perhaps even going as far as to physically intimidate those who cross his path in Konoha.
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.
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 Naruto might feel overshadowed by the Konoha 12. They all have their own unique skills and family backgrounds. For example, Sasuke is always seen as a prodigy. Naruto, who grew up lonely, could feel a sense of envy or resentment towards them which might be explored in the fanfiction. Also, the Konoha 12 might have some unspoken rules or a clique - like environment that Naruto doesn't fit into, making him develop negative feelings in the context of the fanfiction.
The story would deviate from the original themes of unity and friendship. Naruto's hatred could split Konoha into factions. This would mean different training regimens, different missions, and different loyalties. For example, Naruto might start his own group of ninjas who share his views, which would completely change the power dynamics in the village.
Well, it completely flips the script. In the original story, Naruto loves Konoha deeply. But in this fanfiction, his hatred changes the whole dynamic. For instance, his relationships with his friends like Sasuke and Sakura would be drastically different. Instead of protecting the village together, they might be on opposing sides.
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.
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.
