There could be. Fanfiction allows for a wide range of interpretations and alternate storylines. But it's a really extreme and disturbing concept considering the bonds that Naruto, Sakura, and Sasuke share in the official story. It would be a very different take on the characters, and most fans who love the original story would probably find it hard to accept.
This type of fanfiction concept is really out of the ordinary. Naruto's character is built on his values of friendship, loyalty, and his dream of becoming Hokage. Killing Sasuke would mean betraying all of that. However, in a fanfiction, the author might be exploring the 'what - if' scenario. For example, what if Sasuke's actions against Konoha were so heinous that Naruto felt he had no choice? But still, it's a far - fetched and very different view from the original Naruto we know.
This kind of fanfiction usually explores alternate storylines and character dynamics. It might be based on intense conflicts or unexpected plot twists.
Yes, there are likely some fanfics out there with such a plot. Fanfiction is a creative space where authors explore different scenarios. However, it goes against the general narrative of the Naruto series where Naruto is more about saving Sasuke.
It's not a very common trope. Most Naruto fanfictions focus on their friendship or the original storylines. Killing off a major character like 'female Sasuke' (assuming it's a gender - bent or AU version) goes against the essence of the Naruto - Sasuke relationship in the main series which is more about rivalry and redemption. So it's not something you'll see often in mainstream fanfiction.
In Naruto fanfiction, the idea of Sasuke killing Naruto is not overly common but does exist in some darker or alternate universe scenarios. Some writers might explore this to show extreme character development or a drastic change in the story's direction. However, it goes against the core of the original series where their relationship is more about rivalry and ultimately friendship.
It's controversial. Naruto and Sasuke have a long - standing relationship that fans have come to expect a certain development from. Naruto has always been trying to save Sasuke, not kill him. In fanfiction, while there is creative freedom, this concept is against the grain. But some writers might use it to show a extreme breakdown of their relationship due to some unforeseen and very dark circumstances, like if Sasuke was completely consumed by evil and there was no other way. Still, most fans would be shocked by this idea.
Well, it completely shatters it. Their relationship which was built on rivalry, friendship, and a sense of mutual understanding is now gone. It's a tragic end to what could have been a great story of redemption and friendship.
One possible reason could be that Sasuke might have gone too far in his pursuit of power even after the war. He could have been a threat to the newfound peace in the ninja world, and Naruto, as the protector of peace, might have felt he had no other choice.
It's relatively rare. In the Naruto fandom, Naruto, Sasuke, and Sakura are central characters with complex relationships. Naruto and Sasuke are rivals but also friends, and Sakura is part of their team. Most fanfictions focus on their growth, friendship, or romantic relationships. Killing off two such important characters goes against the general positive and growth - oriented themes that many fans prefer.
