What would be the reactions of other characters in the 'Harry Potter fourth year' fanfic if Barty kills Harry?

One possibility could be that Barty was under some extremely powerful dark magic influence that overrode his sense of right and wrong. Maybe in the fanfic, he was being controlled by a more powerful dark wizard who wanted Harry dead at all costs.

Some might be shocked. Hermione, for example, would probably be very concerned about the use of a Muggle weapon in the wizarding world and its implications. She might worry about how it could change the balance between the Muggle and wizarding communities.

Hermione would probably be extremely curious about the ghouls. She'd want to study their biology, especially the kagune. She might even try to find a way to use her magic to help the half - human, half - ghoul characters like Kaneki deal with their identity crisis.

Well, Ginny would be heartbroken that Harry left. She might have expected to build a life with him after Voldemort was defeated. But she's also a strong character, so she would likely throw herself into her own life, perhaps becoming a star Quidditch player. Neville would be overjoyed that Voldemort was dead. He might take on a role at Hogwarts, teaching herbology perhaps, and sharing his knowledge with the students. As for the other characters in the wizarding world, those who had suffered under Voldemort would be in a state of jubilation and start to pick up the pieces of their lives.

It would be a very dark and unorthodox take on the Harry Potter universe. Harry is not typically associated with using a knife as a weapon in the original series. So, it would likely involve a major deviation from his character as we know it.

It could be a wild and imaginative story. Harry, with his Gryffindor courage, might face off against a Satan - like entity that has somehow invaded the wizarding world. He could use his spells and the help of his friends, like Hermione's vast knowledge and Ron's loyalty, to combat this ultimate evil.

Sakura would probably be shocked. She knew the Akatsuki was powerful, and Naruto killing them all might make her see Naruto in a whole new light, perhaps as a more dangerous or powerful figure than she initially thought. Kakashi, on the other hand, might be worried about the implications. He would be proud of Naruto's strength but also concerned about the power vacuum and how it could affect the balance of the ninja world.

Some characters might be amused. For example, Ron would probably find the wilder and more comical fanfictions really funny. He'd be laughing out loud at the absurd scenarios where he's made into a heroic food - loving wizard who saves the day with a well - timed puking pastille.

I'm not sure if there is such a specific 'Harry Potter Kills with a Knife' fanfic. There are countless fanfics out there, and some might have very unusual or dark concepts like this, but it's not a common or well - known one in the mainstream Harry Potter fanfic world.

Hermione, on the other hand, could be more understanding. She might see it as Harry expressing his individuality. She could be supportive and even defend Harry if others are mean about it. In many fanfics, she's the one who tries to promote acceptance. She might say that just as witches can wear trousers, wizards can wear dresses if they like.
