One common plot could be that the sister has a different ideology. For instance, she might believe in a more radical approach to achieving peace in the ninja world compared to Naruto's more inclusive and forgiving way. This difference could lead to clashes and eventually Naruto's hatred. Another plot could be a power struggle. If the sister is extremely powerful and uses her power in a way Naruto doesn't approve of, like being cruel to weaker ninjas, it could make Naruto hate her.
He could hate them because he felt they were absent during his difficult childhood. Naruto faced a lot of loneliness and bullying, and if he thought his parents could have prevented it but didn't, that would breed hatred.
Maybe it's because Aphrodite's powers and the way she uses them are at odds with Naruto's own beliefs. Naruto believes in self - improvement through training and facing challenges head - on. If Aphrodite uses her love - related powers in a way that seems unfair or goes against Naruto's sense of justice in the fanfic, he would dislike her. Like if she uses her powers to manipulate people's emotions for her own gain, which is something Naruto would oppose.
The fanfic changes the relationship by introducing a negative aspect. Normally, Naruto values family and friendship. But here, if he hates his sisters, it means his family unit is not as harmonious as in the original story. It also might affect how he interacts with other characters in the story. For instance, if his friends try to reconcile him with his sisters, it could create new storylines and tensions. And it could also change how the village views Naruto, as a person who has family issues.
Well, it could be a combination of things. Maybe he saw through some hidden agendas of the village elders or was constantly overlooked for important missions despite his skills. Maybe there were trust issues with his teammates or mentors that built up over time and caused this hatred.
The MC's hatred for the village could cause him to go on solo missions that go against the village's interests. Maybe he'll refuse to follow orders in critical situations or even try to undermine the village's leadership. It's a recipe for lots of drama and intense storylines.
In a 'Naruto abandoned for his sister' fanfic, perhaps there's a prophecy that only one of them can bring peace to the village. The elders, misinterpreting it, choose the sister and abandon Naruto. Naruto then goes on a journey outside the village, meets new friends and allies, and discovers new powers. Meanwhile, the sister is having her own struggles within the village, like dealing with the pressure of being the 'chosen one' and realizing that Naruto's abandonment might not have been fair.
Well, it could be that Naruto has been betrayed too many times. Maybe he discovers that some of his closest friends have been using him all along for their own gains. So he starts to hate everyone, and the story could be about his journey of isolation and self - discovery as he tries to come to terms with his new feelings.
Often in these fanfics, Sakura might make fun of Naruto's dreams or goals in a very mean - spirited way. This constant put - down could lead Naruto to hate her. Also, if Sakura were to side with Naruto's enemies in the fanfic for some reason, like being brainwashed or having a hidden agenda, it would be a likely cause for Naruto's hatred.
