One common theme could be the exploration of power and corruption. Harry might be depicted as being corrupted by power, which leads him to kill Dumbledore. Another theme could be betrayal. It shows a complete break from the loyalty that was so central to the original story. And there could also be a theme of misinformation, where Harry acts based on false information.
One possible motive could be a misunderstanding. Maybe Snape is framed for something really bad, like a dark magic plot against Hogwarts. Harry, in his haste to protect the school and his friends, believes Snape is guilty and takes drastic action. Another reason could be if Snape accidentally endangers someone Harry loves dearly, like Ginny or Ron, and Harry's emotions get the better of him in the heat of the moment.
In some fanfictions, Snape kills Dumbledore as part of a greater plan. Maybe Dumbledore was already dying or had some sort of incurable dark magic on him, and Snape's act was a mercy killing. It could also be a complex plot twist where Snape is actually trying to protect the wizarding world from a greater threat that only he and Dumbledore knew about.
It would be very difficult. However, if the writer were to explore some sort of dark magic corruption on Harry. For example, if he was somehow influenced by a powerful dark object or spell that made him lose his sense of self and morality. But still, it would be a huge stretch from the original concept of Harry's character.
Not really. While the Harry Potter fanfiction world is vast and full of diverse and creative plots, the idea of Draco killing Dumbledore specifically for Hermione is quite an out - there concept. Most fanfictions tend to follow more traditional character arcs or explore different romantic pairings in more typical ways. However, there are always some very unique and niche fanfictions that might feature such a plot.
In the fanfiction, Snape could protect Harry from Dumbledore by using his skills in potions. For example, he might create a potion that hides Harry's magical signature from Dumbledore's detection. Or he could use his knowledge of the Dark Arts to counter any spells or charms that Dumbledore might use to keep tabs on Harry. Snape is very intelligent and resourceful, so he could find various ways to physically and magically shield Harry from Dumbledore.
One reason could be that Snape has his own complex sense of loyalty. He may feel that Dumbledore's plans for Harry are too dangerous or not in Harry's best interest in some ways. He has a long - standing relationship with Harry's mother, Lily, and perhaps through that connection, he wants to safeguard Harry from any harm that might come from Dumbledore's actions or decisions.
I don't have any novels about the era of the Big Four. However, if Harry Potter and Severus, Snape, Albus, and Dumbledore were to travel back in time to the era of the Big Four, then the story might involve the history, politics, culture, and other aspects of the Wizarding world. At the same time, there might be other characters and storylines. Can you give me more information? I will do my best to help you.
It's a very controversial theme. In the original 'Harry Potter' series, both Snape and Dumbledore are complex and important characters. Dumbledore is a mentor figure to Harry, and Snape has a very complicated relationship with Harry as well. For fans who love the original story, the idea of Harry killing them goes against the essence of the characters' development and the overall moral and emotional fabric of the series.
In the original 'Harry Potter' series, the relationship between Harry and Snape was one of mutual dislike but also a certain level of respect in the end. However, in this fanfiction, it's a complete break. The fanfiction might change the power dynamics at Hogwarts as well. Snape was a key figure in the school's hierarchy, and his death at Harry's hands would send shockwaves through the staff and students, unlike anything in the original story where his death was a heroic sacrifice.
