I'm not sure about the specific plot of this fanfiction as it sounds rather unorthodox. It could be a very dark or alternate - universe take on the Harry Potter world where Harry goes against the Weasleys for some extreme reason.
Perhaps in this fanfiction, there is some sort of misunderstanding or dark magic influence that makes Harry think the Weasleys are a threat to something he holds dear, like Hogwarts or the wizarding world at large. So he decides to take actions against them, which is quite a departure from the original positive relationship between them in the official books.
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.
It could mean that in this fanfiction, Harry is in a situation where he somehow causes harm or destruction to the Weasley family. Maybe he's under some dark influence or there's a big misunderstanding that leads to him acting against the Weasleys.
No, it's not common. Usually, fanfiction focuses on positive relationships between characters, especially Harry and the Weasleys who are often portrayed as a close - knit family. So this would be a rather unusual and dark theme.
Perhaps in this fanfiction, Harry discovers some dark secret about the Weasleys that he believes endangers him or the wizarding world. His revenge could then be to expose this secret in a way that embarrasses the family. He might use his influence and knowledge to make sure the Weasleys are shunned by some in the wizarding community.
It could be that there's a powerful enemy that has taken over Hogwarts and Harry, in a desperate attempt to stop this evil from spreading, resorts to destroying the school. He might think that rebuilding it later is better than allowing it to be used for evil purposes. For example, if Voldemort had found a way to permanently taint the magic of Hogwarts, Harry might see destruction as the only option.
Well, perhaps Harry discovers some dark secrets within the Ministry that are so evil he decides to take it down. Maybe they're involved in some sort of illegal dark magic experiments or corrupt deals with dark wizards.
I'm not sure specifically as there could be many different interpretations in fanfiction. It might involve Harry making choices that have dire consequences for the future in the fictional wizarding world, perhaps through the misuse of magic or making wrong alliances.
I'm not sure if it's a new plot trend. Fan culture is so diverse that there could be some individual works exploring this idea, but it might not be widespread enough to be considered a trend. It could be a unique take by a particular author or group of fans who want to explore a different aspect of the Harry Potter universe.
Well, it's a very dark and unorthodox concept. In the original series, Dumbledore is a mentor figure to Harry. In fanfiction, if Harry were to destroy Dumbledore, it could signify a major deviation from the core values of the original story. It might be exploring themes of betrayal, a different view of power dynamics, or a radical re - interpretation of the characters' natures.
I'm not entirely sure specifically what that particular fanfiction is about. It could be a creative take where Harry Potter, using his magic perhaps, destroys some sort of blocks in a unique and made - up scenario. Maybe it's related to a magical construction that has gone wrong and he has to break the blocks to fix things.
