Maybe the writer just wants to be different. Since Naruto is usually seen as a hero, they might think it's edgy to write him as a loser.
It could be that the writer has a different interpretation of what makes a 'winner' or 'loser'. They might focus on Naruto's early failures and not give enough credit to his later success. For example, in the beginning, Naruto did struggle in school and with making friends, but that was just the start of his story. Or perhaps the writer is just trying to create a unique storyline that goes against the common perception of Naruto.
There could be several reasons. One might be that they simply have a dislike for the Naruto franchise and are using this extreme concept as a form of protest in a very unorthodox way. Another possibility is that they are just exploring some really dark and unethical ideas for the sake of creativity, without considering the negative impact it could have on the fans of the series. It's also possible that they don't fully understand the significance and positive influence of the Naruto character and are just making a random and inappropriate statement through this fanfiction.
Maybe for shock value. Some people want to create something that stands out and goes against the norm, so they take a well - loved character like Naruto and give him a completely opposite and dark role.
It could be a symbolic way of showing the destruction of hope. In the Naruto series, Naruto represents hope. By having Hinata kill him, the writer might be trying to convey a sense of hopelessness or the end of an era. This could be part of a larger, more complex story about the fall of the ninja world as we know it in the Naruto franchise.
Maybe the writer wants to explore a darker or more alternative version of Naruto. It could be a way to break the traditional view of his character and see how the story would unfold if he was cold - hearted.
Some might do it for shock value. They want to create something that stands out from the typical, positive fanfiction about Harry Potter. By giving him such an out - of - character trait like kleptomania, they hope to get more attention, even if it's negative attention.
His motivation could be freedom. He may feel restricted by the gods' rules and demands, so he decides to flee to gain his own freedom.
One possible motivation could be power. Orochimaru is always seeking more power, and Naruto has the power of the Nine - Tails. He might think that by killing Naruto and somehow harnessing the Nine - Tails' power, he could become even stronger.
One possible motivation could be to create drama. By having Naruto kill Sarutobi, it would shock the readers and create a huge rift in the story's world. It might also be a way to explore Naruto's dark side that we rarely see in the official story.
Some people might write it just for the shock value. They want to create something that goes against the norm and surprises readers.
Maybe it's a way to protect the village. The ravens could act as an early warning system. They can fly over Konoha and the surrounding areas, and if they detect any incoming threats, they can quickly report back to Naruto. It's a form of aerial defense that can complement the existing ninja guards.
