There's no real way to know for sure without looking at fanfiction platforms' statistics. But considering how beloved the Weasleys are in the 'Harry Potter' world, and how Harry is seen as a hero, this kind of fanfiction that turns that on its head might not be as well - received as more positive or canon - compliant fanfictions.
I'm not sure if it's a popular fanfiction. It's such a dark and against - the - grain concept for the 'Harry Potter' fandom that it might not have a large following. Most fans are used to the positive relationships between Harry and the Weasleys in the original series.
I haven't actually read this specific fanfiction, but it's a very dark and disturbing concept. In the normal 'Harry Potter' universe, Harry and the Weasleys are friends. So this fanfiction probably involves some sort of dark plot twist or alternate reality where Harry turns against them for reasons that could range from being influenced by dark magic to some misinterpreted prophecy or a huge misunderstanding.
Probably not. Given that the Weasleys are beloved characters in the Harry Potter universe, a fanfiction with such a negative and extreme concept as Harry destroying them is likely to be off - putting to a large number of fans. Fans usually look for fanfictions that expand on the positive aspects of the story, like friendships and adventures, rather than something so dark and against the norm.
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.
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.
Definitely Harry Potter himself. He is the main character in the original series, and in fanfiction, his relationship with the Weasleys can be explored in many ways, like his bond with Ron as his best friend and his relationship with the Weasley parents as a sort of surrogate family.
One possible reason could be that Harry has post - war trauma. He might have seen so much death and destruction during the war that he doesn't want to bring his darkness and pain to the Weasleys. He may think that staying away is a way to protect them from his own emotional turmoil.
At first, the Weasleys might try to reach out to Harry. But as he continues to avoid them, they could start to feel rejected. This might lead to some resentment building up, especially among the younger Weasleys who don't understand why Harry is acting this way. For example, Ron might be really frustrated as he considered Harry one of his best friends.
The relationship becomes more protective. The Weasleys will be more cautious about Harry's well - being.
In this fanfiction, the betrayal might also stem from jealousy. Harry is often in the spotlight, and the Weasleys, who have always been a big family but not always in the center of attention, could let envy get the better of them. This could lead to actions that Harry perceives as betrayal, like spreading rumors or withholding support when he needs it most.
I'm not sure if it's popular. It depends on various factors like how well - written it is, how unique the concept is within the large Harry Potter fanfiction community, and how much it gets promoted. There are so many fanfictions out there that it can be hard for any one to stand out.
