It could be that the paperwork reveals some hidden magical secret or legal loophole that enables the revival. Maybe it involves ancient spells or forgotten magic rituals documented in the paperwork.
The paperwork might contain instructions on performing a complex magical ceremony or accessing a hidden magical realm where the power to revive exists. It could also be a set of permissions or magical licenses needed to undertake the revival process.
In some fanfictions, Harry might use extremely powerful and ancient magic. Maybe he discovers a long - lost spell during his adventures that has the power to reverse death. For example, he could find a spell hidden in a forgotten corner of the Hogwarts library that was created by a powerful wizard in the past but was deemed too dangerous to be used.
In some fanfictions, Naruto might find a super - powerful jutsu or artifact. For example, he could discover a long - lost forbidden jutsu that has the power to bring the dead back to life. Or perhaps he stumbles upon a magical item during one of his adventures that is said to be able to revive the deceased.
The original Harry Potter story has a strong family - love - centered theme. Harry's parents' love for him was so strong that it protected him even after their death. In the 'Harry Potter hates his parents' fanfic, this central theme is completely changed. It's a deviation that changes the whole dynamic of the relationships in the story. It's like changing the core of a flower, everything else about the story will be affected, such as Harry's relationship with his friends who also respected his parents.
He would be overjoyed. It's his parents, after all.
Well, it could make him more independent. Without the initial love and protection from his parents, Harry has to learn to fend for himself at a very young age. So when he gets to Hogwarts, he might be more likely to take risks and not rely on others as much.
He might be extremely angry and confused. After all, parents are supposed to be the ones you can trust the most. He could start to question everything he knew about his family and himself.
Harry could start writing in a journal, documenting his feelings. This would be a way for him to process his emotions privately. He might also find solace in nature, spending time in the Forbidden Forest, where he can be alone with his thoughts and away from the prying eyes of those who pity him.
Well, it might start with Harry having doubts about his parents. Then, as he digs deeper into their past, he could start to distance himself. Eventually, he publicly disowns them, which would shock the wizarding community. This could lead to him being ostracized by some and supported by others who also have doubts about his parents' actions.
It could be due to a sense of abandonment. Fanfic writers might explore the idea that Harry, growing up without his parents, feels resentful. He may see other kids with their families and, in his confusion and pain, start to hate his parents for leaving him alone in the world, even though it was not their choice.
One possible reason could be that in the fanfic, the author might twist the story to make it seem like his parents' actions had unforeseen consequences that affected Harry negatively. For example, their fight against Voldemort led to Harry being an orphan and having to bear a great burden from a young age.
