Maybe he has been betrayed too many times in the past. For example, in the original story, some so - called friends or allies might have let him down, and this experience makes him overly cautious in the fanfiction.
In some fanfictions, the author might want to create a new plot twist. Maybe they introduce a misunderstanding, like Hermione accidentally getting involved in something that looks suspicious to Harry. For example, if she's caught in a secret meeting that she can't immediately explain, Harry could start to lose trust.
Maybe in the fanfiction, Harry has had bad experiences with adults. For example, some adults in the story might have betrayed his trust in the past, so he becomes wary of all adults.
Maybe he has read some really bad Order fanfictions before that were full of inaccuracies or out - of - character portrayals, which made him lose trust in this type of fanfiction.
It might start with small incidents. For example, Ron being late to meet Harry a few times without a proper explanation. This can plant the seeds of doubt in Harry's mind.
Another reason could be personal insecurities on Harry's part. Harry has been through a lot and might be over - analyzing Ron's behavior. He could be projecting his own fears onto Ron. For example, if Harry is worried about being betrayed again like he was by some people in the past, he might start to doubt Ron even without solid evidence.
Most likely. The 'Harry Potter' series is all about friendship and family, and the Weasleys are like a second family to Harry. To have him kill them is a huge deviation from what fans expect and cherish about the story.
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.
Well, Harry Potter is a character in the original story. Fanfiction often takes the original story in all kinds of wild and different directions. Harry, being from the original, proper story, may not be able to understand these new and sometimes out - of - the - box interpretations that fanfiction presents. It's like he's from a very specific world, and fanfiction creates a whole bunch of new worlds based on that, which he has no knowledge of.
That's a very dark and non - canon concept. In normal 'Harry Potter' lore, Harry and the Weasleys are friends. This fanfiction might be exploring a very different, twisted alternate reality where Harry has been turned evil or something has gone horribly wrong in the wizarding world to make him kill the Weasleys.
