It could be a creative exercise in exploring how a single event, like Kushina killing Naruto, would change the entire Naruto universe. Writers might be interested in seeing how other characters would react, how the story would progress without Naruto, and how the themes of the original story would be altered. For instance, the theme of friendship and mentorship would be severely affected. It's also possible that the writer wants to shock the readers and make them think about the characters in a completely new light.
Well, writing a 'zeus kills percy' fanfiction could be a way for the author to delve into the themes of mortality and power in the Percy Jackson universe. In the original series, Percy is often seen as invincible in a sense, so by having him killed, it makes the world seem more dangerous and unpredictable. It also allows the writer to rewrite the story in a completely new direction, perhaps exploring a post - Percy world where new heroes or anti - heroes emerge. It might also be a way to comment on the flaws in the existing power structure within the mythological world of the series.
It could also be an exploration of character development in extreme situations. What would Edward become if he did such a thing? How would the other characters change? Writers might use this extreme scenario to show how the characters would react and grow, or in this case, maybe degenerate in a different way compared to the original story.
Some writers might want to explore dark and extreme scenarios. It's a way to break the norms of the usual heroic storylines. They may be interested in seeing how the characters and the Marvel universe would react to such a tragic event.
The implications would be huge. It would completely shatter the positive family image that the Naruto series usually portrays. Fans who love the relationship between Naruto and his parents would be very shocked and possibly offended.
One reason could be to explore a unique power combination. Naruto is known for his own powerful jutsu like the Rasengan, and combining it with the Susanoo, which is a very powerful Uchiha ability, makes for an exciting and fresh concept in the Naruto universe.
Well, it could be for a plot device. Writers might want to create a more complex and angsty story. By having Kushina ignore Naruto, they can explore themes of abandonment and self - discovery. It adds a layer of drama to Naruto's character development.
Maybe to focus on other aspects of Naruto's character like his determination. Without love in the story, it can show his single - minded pursuit of being a great ninja.
Some writers might write it to explore the darker side of characters. They want to see how a usually positive character like Rias can turn bad and how Naruto would react in such a situation. It's all about exploring different character dynamics.
One possible reason could be a misunderstanding. Maybe Minato thought Kushina had done something to endanger Naruto when in fact she hadn't. In the heat of the moment, he lost his temper and slapped her.
One reason could be to explore alternative scenarios. They might think 'what if Naruto had this super - broken power?' and write a fanfic around it. Also, it could be a way to stand out. In a sea of Naruto fanfics, having a really out - there concept like a 'broken' Naruto might attract more readers.
