Maybe the writer wants to create a more cerebral or detached version of the story. Without emotions, the focus could shift more towards the pure logic and mechanics of the wizarding world. It could be an experiment to see how the story unfolds when the emotional element is removed. Another reason might be to show the contrast between a normal, emotional Harry and this new, emotionless version. It can highlight the importance of emotions in the original story.
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 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.
One possible reason could be to protect himself from the pain and loss he has endured. After all he's been through, like the death of his parents, Sirius, and so many others, turning off his emotions might seem like a way to avoid further hurt.
Perhaps some writers want to break free from the traditional view of Harry. They might think that by making him a 'bad boy', they can create more interesting conflicts and relationships within the fanfiction. Another reason could be to appeal to a niche audience who might be interested in seeing a darker or more non - conformist version of Harry Potter. It gives the writer a chance to re - imagine the whole 'Harry Potter' universe from a different perspective.
One possible reason could be miscommunication. Maybe Ron said something that Harry misinterpreted, leading to the distrust. For example, if Ron made a joke about Harry's abilities in a time of stress, Harry might take it the wrong way.
It could also be that in the fanfiction, McGonagall has shown some form of bias. Maybe she seems to favor certain students or groups over others, and Harry, being the one who always stands up for fairness, starts to distrust her when he notices this behavior. He might feel that she is not as just as he once thought her to be.
It could also be due to some actions of McGonagall that seemed suspicious to Harry. Perhaps she made a decision regarding Hogwarts or Harry's safety that Harry didn't fully understand at the time. In the complex world of the wizarding school, decisions are often made with many factors in mind, but Harry might not be aware of all of them, leading to his distrust.
It could also be that Harry has his own ideas about how to deal with the situation at hand. He might think that Dumbledore's approach is too cautious or too risky. For instance, if there's a threat from Voldemort, Harry might believe that a more direct and aggressive strategy is needed rather than following Dumbledore's more calculated and long - term plans.
It could also be due to a long - standing pattern of behavior. If Ron had been constantly critical or undermining of Harry in the fanfiction, Harry might reach a point where he just can't forgive. Say Ron always made fun of Harry's decisions in front of others, which gradually eroded Harry's trust and patience.
