What are the possible reasons for a good boy to disobey his parents in a story?

Sometimes the parents' demands might be unreasonable or not in the best interest of the boy, leading to his disobedience. Another possibility is that the boy might have misunderstood the instructions.

Maybe the parents have some mental health issues or are under the influence of a cult. That could make them do such a crazy thing.

One possible reason could be that the parents have some unfulfilled desires related to having a girl. Maybe they always dreamed of having a daughter and are trying to create that situation by changing their son's appearance or upbringing. But this is a wrong approach as it doesn't respect the child's identity.

One possible reason could be some past misdeeds by the parents. Maybe they were neglectful or made decisions that seriously affected Ciel's life in a negative way in the context of the fanfic.

Perhaps Naruto's parents were cursed or had some sort of premonition about a great danger coming to Naruto if he stayed with them. They believed that by separating from him, he would have a better chance of survival. Fanfiction writers often explore these kinds of emotional and complex scenarios to give a different perspective on Naruto's origin.

One possible reason could be a misunderstanding. Maybe he discovers some secrets about his parents that he misinterprets. For example, if he finds out they were involved in some dangerous or morally ambiguous activities in their youth that he doesn't fully understand at first.

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.

One possible reason could be that he discovers some long - hidden family secrets that make him question his parents' actions or decisions. Maybe he finds out about some dark deeds in their past that he can't overlook.

One possible reason could be that they are too involved in their own shinobi duties. The world of ninjas is full of dangerous missions, and they might be constantly away on important tasks, leaving Naruto feeling neglected.

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.
