His friends would be worried and try to reach out to him. They might face rejection as Naruto, consumed by hatred, could push them away. For example, Sakura might try to talk some sense into him but be met with anger.
Well, if Naruto is consumed by hatred in a fanfic, he may start to use his powers in a more aggressive and less controlled way. He might isolate himself from his friends, like Sasuke did in the original series when he was on his path of revenge. His appearance could even change to reflect his inner turmoil, with a darker look in his eyes and a more menacing stance.
She could start by listening. Just being there to let Naruto vent out all the reasons for his hatred. Then, she might share her own wisdom. If she has some sort of special power or knowledge, she could use it to show Naruto that there's more to life than his hatred. For instance, if she can show him different futures or possibilities that don't involve him being consumed by hatred, it could be a start.
Well, if Naruto is consumed by hatred and there's a female Kyuu in the picture, their relationship could be really complex. Kyuu might try to reach out to the Naruto within the hatred. Maybe she'd use her own experiences to relate to him. For example, if she has had her own share of hardships that led to feelings similar to hatred in the past, she could share those stories with Naruto. It could be a bumpy start, but gradually they might find common ground and start to heal each other.
Naruto, being consumed by hatred, would likely become more brooding and intense. The fem Kyuubi could start off as a mysterious figure but gradually develop into a more empathetic character as she gets closer to Naruto. She might help him grow out of his hatred by showing him different ways of looking at his past and the world around him.
One possibility is that Naruto, filled with hatred, forms an unexpected bond with the female Kyuubi. Maybe the story could explore how they deal with Naruto's inner demons together. The fem Kyuubi might offer a different perspective on Naruto's struggle and help him find a way to overcome his hatred.
Naruto might also face hatred by becoming stronger. He trains harder and shows his opponents that he is not someone to be underestimated. For instance, if a group of rogue ninjas hates him because they think he's too idealistic, he proves them wrong by defeating them in combat and showing that his ideals are what make him strong.
Maybe in the fanfic, Naruto discovers that his parents' death was not as straightforward as he thought. If he finds out that some powerful individuals in the village were actually involved in a conspiracy that led to their deaths, this revelation could be the trigger for his descent into hatred. He might then turn against the village and its leadership, using his powerful jutsu not for protection but for vengeance.
It could be the Hidden Leaf Village's elders. If they are shown to be manipulative and using Naruto for their own political gains, and Naruto eventually finds out, they would become the main antagonists. He might see their actions as the root of all his problems and turn his hatred towards them for exploiting him.
One interesting concept could be exploring how the curse of hatred affects different characters in new and unique ways. For example, it might show how a minor character is deeply influenced by the hatred that circulates in the Naruto world, leading to unexpected actions or alliances.
