One reason could be the author wants to create a unique and edgy story. By making Harry Potter not care about anyone, it's a complete subversion of the well - loved character. It grabs readers' attention.
It could also be a way to explore the idea of isolation. What if Harry Potter, for some reason, felt so alone that he just shut everyone out? This fanfiction concept might be a way to dig into that feeling of loneliness and how it can change a person's attitude towards others, even if it's a very different Harry Potter from the original.
Maybe the author had a different view of how power could corrupt. If Harry Potter suddenly got a lot of power and it made him uncaring, it would be a different take on the idea of power in the wizarding world. He could be so focused on his own goals that he forgets about others.
Well, it could be that the fanfiction is set in a very different universe where Naruto has different upbringing or experiences. But this is quite a stretch because Naruto's caring side is so deeply rooted in his story. It might also be that the writer is simply trying to create shock value by presenting such a counter - intuitive view of Naruto. But in general, it's not in line with the essence of Naruto as we know him from the original series, and it might be a bit of a gimmick to make the fanfiction stand out in a sea of more traditional Naruto stories.
One possible reason could be a long - held grudge. Maybe there were past incidents in the family that made Harry feel betrayed or neglected. For example, if his family always favored another sibling over him, it could lead to his apathy.
One possible reason could be to explore a different side of the character. By taking away his emotions, the writer can show how much emotions actually contribute to his actions and relationships. It's like a 'what if' scenario.
Another reason could be outside influence. If there were dark forces trying to drive a wedge between Harry and the Weasleys, they might plant false ideas in Harry's mind. This could make Harry question the Weasleys' loyalty, even though they are truly his friends.
Perhaps there were some secrets that Ron was keeping from Harry. In the wizarding world, secrets can be a big deal. If Ron had a secret related to his family or some other important matter and Harry found out about it in a way that made it seem like Ron was hiding something bad, it could lead to Harry not trusting him. Also, Ron's friendship with other characters might make Harry jealous or suspicious. If Ron was getting closer to someone Harry didn't trust, it could spill over and make Harry question Ron's loyalty to him.
One reason could be to explore Naruto's character independently. Without the focus on his relationship with Sasuke, the writer can delve deeper into other aspects of Naruto's personality, like his dreams for the village, his relationships with other characters like Kakashi or Iruka. It's a way to break free from the over - emphasized bond in the original story.
It could also be due to some sort of mind - control or curse. In the Naruto universe, there are many powerful jutsus and dark magics. Perhaps an enemy has cast a spell on him that makes him not care about his own life. This would be a dangerous situation as he could be easily manipulated into dangerous situations without self - preservation.
Well, in the original series, Harry Potter is a very caring person. He cares about his friends like Ron and Hermione deeply. He also cares about the fate of the wizarding world. But in this fanfiction, it's a complete departure. Maybe the author wants to explore a different side of Harry, like if he had been through some really tough experiences that made him seem uncaring. But it goes against what we know of his core character.
Well, it could be a way to show Harry's rebellious side. He's always been a bit of a rule - breaker, and wearing heels could be seen as a new form of that. Maybe the author of the fanfiction wants to create a more unique and modern version of Harry. Also, it could be related to a plot where Harry has to disguise himself in some strange way and heels are part of that disguise. It gives a whole new dimension to his character and the story.
One possible reason could be past betrayals. Maybe he was let down by his friends or family in the fanfiction's storyline. For example, if someone he trusted shared his secrets with the wrong people, it would make him hesitant to trust anyone again.
