In the 'Harry Potter hates his sister' fanfiction, what could be the possible reasons for Harry Potter's hatred towards his sister?

It could be due to a misunderstanding. Perhaps there was an incident where his sister was involved, but Naruto misinterpreted her actions as something malicious against him. Like she might have accidentally broken something precious of his and he thought it was on purpose.

Well, the Dursleys were extremely cruel to Harry. They locked him in his cupboard under the stairs for a long time. They also tried to prevent him from knowing about his magical heritage, which was a big part of who he was. Harry must have felt a great deal of resentment towards them for suppressing his true self.

Another possibility is that there is some sort of personal misunderstanding between them. Maybe Susan Bones accidentally reveals one of Harry's secrets or makes a wrong assumption about him in public, which embarrasses Harry and leads to his hatred. Also, it could be that her family background or family connections play a role. If her family has some past issues with Harry's family or friends, it might fuel Harry's negative feelings towards her.

One possible reason could be that he might feel abandoned. Growing up without them, he could resent the fact that they left him an orphan. He might think that if they were really so great, they would have found a way to survive and be there for him.

One possible reason could be a misunderstanding. Maybe some false information was spread about Kushina that made Naruto believe she had wronged him in some way. And for his sister, perhaps there was some sort of jealousy or miscommunication. For example, if his sister got more attention from their father or something similar.

Perhaps they have wronged Naruto in some way in the fanfiction. They could have betrayed him, like telling his secrets to others or getting him into trouble on purpose. This would lead to Naruto developing hatred towards them.

One possible reason could be the way the Dursleys treated him. They were cruel, made him live in a cupboard, and constantly belittled him. This kind of mistreatment over the years could easily lead to hatred. Another aspect could be the lack of connection to his wizarding family that he was not aware of for a long time. He might feel angry at his parents for leaving him in such a situation without any real protection from the Dursleys.

One possible reason could be Snape's past experiences. Maybe he had a difficult childhood himself and doesn't know how to handle having a son. He might project his own insecurities and traumas onto Harry. Another reason could be that he sees too much of Harry's father in him. Since Snape had a long - standing feud with Harry's father, seeing those traits in Harry could trigger his hatred.

One possible reason could be his lingering resentment towards James Potter, Harry's father. Snape and James had a long - standing feud during their school days. Since Harry looks a lot like James, Snape might be transferring his old grudges onto Harry.

One possible reason could be jealousy. Maybe the sister is more favored by the villagers or has some special abilities that Naruto feels overshadow his own. This could lead to a sense of envy and ultimately hatred.
