In fanfiction, when Harry doesn't trust Dumbledore, it often leads to a shift in the power balance. Harry might take more matters into his own hands, which could have both positive and negative outcomes. Positively, he could become more self - reliant and develop his own unique way of dealing with threats. Negatively, he could end up putting himself and others in more danger without Dumbledore's wisdom to guide him.
One consequence could be a breakdown in their friendship. His friends might feel hurt and start to distance themselves from Harry. For example, Hermione, who is very loyal, might be deeply offended if Harry constantly doubts her.
One possible reason could be that Harry discovers some hidden actions of Dumbledore that seem manipulative. For example, if Dumbledore has been keeping secrets about Harry's past or his destiny without fully explaining them. Harry might feel used or deceived, leading to his distrust.
One reason could be jealousy. In some fanfictions, if Harry has become very famous and powerful, he might think the Weasleys have different motives for being around him, like using his fame for their own gain. So he starts to lose trust in them.
Fanfiction can sometimes be full of wild speculations and ideas that go against the established rules of the wizarding world. Harry Potter knows how things really work in his world, so he wouldn't blindly trust something that contradicts that knowledge.
One possible reason could be that Harry breaks school rules in the fanfiction. For example, if he ventures into the Forbidden Forest without permission. Dumbledore is strict about the safety of students and such disobedience might lead to punishment.
One consequence is that Harry may lose trust in Dumbledore. In fanfic, this can lead to Harry making decisions on his own, without relying on Dumbledore's guidance. For example, he might go off on his own to search for answers about his parents' death or Voldemort's secrets.
The consequences might include a change in the outcome of the fight against Voldemort. If Dumbledore's plan was a sure - fire way to defeat Voldemort in the long run, Harry derailing it could lead to either a more difficult victory or even a defeat. Also, Harry himself could face personal consequences. He might lose the trust of his friends who believed in Dumbledore's wisdom. His reputation in the wizarding world could be tarnished as people would think he was acting recklessly.
In a fanfiction, Dumbledore might steal out of desperation. Suppose there was a situation where a curse was about to be unleashed on Hogwarts, and the only way to stop it was by stealing a particular ingredient for an antidote from a place where it was not supposed to be taken. Dumbledore, seeing no other option, decides to steal it. His motive here is to save the school and its students, even if it means breaking the rules.
Well, in certain Harry Potter fanfiction, Dumbledore can come across as insane. It really depends on the writer's interpretation and the direction they want to take the story. Some might do it for shock value, to create a more edgy or different take on the well - known character. However, the canonical Dumbledore was a highly intelligent and calculating figure, not insane.
If such a fanfiction exists, it could cause a great deal of controversy in the 'Harry Potter' fan community. Many fans who love the original characters and their relationships would be deeply offended. It might lead to a divide between those who think it's just a form of extreme creative license and those who see it as a desecration of the characters and the series' values.
