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 sure if it's popular. Fanfiction can range from very well - known and widely read to extremely niche. Without more information about this specific piece, it's hard to say if it has a large following.
I'm not sure specifically what that particular fanfiction is about. It could be a very dark or alternate - universe take on the Harry Potter story where Harry turns against Dumbledore for some reason, perhaps feeling betrayed or misled by him in this fan - created scenario.
One possible motive could be to explore a dark and alternate universe. The writer might want to see how the 'Harry Potter' world would change if such a drastic event occurred. Another reason could be to analyze the characters from a different perspective. By making Harry the destroyer of Dumbledore, it forces readers to re - evaluate both characters.
In the original Harry Potter series, Dumbledore is a respected and powerful figure who helps Harry on his journey. But in fanfiction with 'Harry Potter destroys Dumbledore', it creates a whole new narrative. It might introduce new conflicts and character arcs. For example, Harry could face a great deal of internal struggle and external backlash for such an act. The fanfiction may also explore different magical elements or political situations in the wizarding world that were not as prominent in the original, as a result of this drastic change in the story.
It shakes the foundation of the trust that fans have in the characters. Dumbledore is often seen as a wise and benevolent figure. If Harry destroys his reputation, it makes fans question all the previous events and decisions that Dumbledore was involved in. For example, his guidance to Harry might now seem suspect.
It could be that Harry finds out about Dumbledore's secrets regarding the Deathly Hallows. If Harry thinks Dumbledore was more interested in the Hallows for his own purposes rather than for the greater good, it might make him hate Dumbledore.
In the 'Harry Potter' fandom, this would be a very controversial concept. Dumbledore is often seen as a mentor and a powerful, positive figure. Having Harry Potter destroy him goes against the general perception of their relationship in the original series. However, in the realm of fanfic, some might explore such a dark and alternative take as a way to examine different character arcs and what - if scenarios, but it would likely be met with a lot of resistance from purist fans.
In some fanfics, Dumbledore having 'babies' is a very strange and often out - of - character concept. Usually, if this idea is explored, it might be in an alternate universe kind of setting. Some fanfics may use it as a shock factor or to create a really different kind of family dynamic within the wizarding world. But it's not a common or canon - like concept at all.
It could be Voldemort. He might have found a way to manipulate Harry into attacking Dumbledore's office. By doing this, he not only causes chaos in Hogwarts but also tries to drive a wedge between Harry and Dumbledore.
