A lot of these fanfictions have a theme of isolation. Naruto is pushed away from Team 7, either physically or emotionally. For example, they might exclude him from important missions or conversations, which makes him resent them. Another plot point could be a shift in Naruto's character. Due to the hatred, he might become more cynical or bitter, and this change in his personality is often explored in these fanfictions.
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.
It could be that in the fanfic, Team 7 starts to act in a way that goes against Naruto's moral code. For example, if they start using cruel or unethical methods to achieve their goals. Naruto, being the character he is, would not stand for such behavior and this could lead to his hatred. Additionally, if there is a personal loss that Naruto experiences which he blames on Team 7, that would also contribute to his negative feelings.
One possible scenario is if Naruto is constantly blamed for the team's failures. For example, if every mission that goes wrong is pinned on Naruto, even when it's not his fault, he might start to hate the team. This could be due to a misperception by the other members or a malicious plot within the fanfiction world.
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.
It completely flips the dynamic. In the original storyline, Team 7 is a close - knit group. But in this fanfiction, Naruto's hatred for them disrupts that unity. It could lead to new alliances and rivalries. For example, Naruto might team up with former enemies who share his dislike for Team 7.
In the original, Naruto's team supports him and they grow together. However, in this fanfiction, the concept of Naruto hating his team means that all those positive interactions and character developments are thrown out. His relationships with his teammates, which were based on mutual respect and trust in the original, are now replaced with negative feelings.
It could cause some division. Fans who like the fanfiction might not understand why Sakura is being 'hated' in it and might defend the work, while those who understand Sakura's character well might side with the idea that she would hate it. This can lead to arguments and a split in the community.
One possible reason could be that the fanfiction misrepresents Sakura's character. Maybe it portrays her in a way that she would never act in the original context of the series, which makes her seem out of character and thus causes dislike. Another reason might be that the fanfiction focuses too much on other members of Team 7 and sidelines Sakura, making her seem less important or relevant than she actually is in the story.
