Sasuke's character would likely become more complex. His act of killing Danzo could push him further into the realm of darkness or, paradoxically, start his journey towards redemption as he realizes the full weight of his actions. Danzo's character, in death, could be revealed in different lights. Maybe his true motives for his actions throughout his life are uncovered, which could affect how other characters view Sasuke's killing of him.
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.
The village's political structure would likely change. Without Danzo, there would be one less power - hungry figure vying for control. The relationship between the Hidden Leaf and other villages might also be affected. Danzo's actions often had far - reaching consequences in international relations. Naruto might face some internal opposition for his actions at first, but in the long run, it could lead to a more just and transparent village governance.
One possible plotline could be Sasuke's revenge-driven journey leading up to the moment he kills Danzo. He might discover new secrets about Danzo's past misdeeds that fuel his hatred even more. For example, he could find out about Danzo's role in the Uchiha massacre in greater detail. Another aspect could be the aftermath of the killing. How does it affect the Hidden Leaf Village? Does it lead to chaos or a new understanding of Sasuke's motives among the villagers?
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.
A possible motive could be a creative exploration of the 'what - if' scenarios. Maybe the writer wants to see how the story would unfold if Sasuke completely lost his way. Another motive could be to create a sense of high - stakes drama. Since Sakura is an important character, her death at Sasuke's hands would be a huge shock.
This kind of fanfiction usually explores alternate storylines and character dynamics. It might be based on intense conflicts or unexpected plot twists.
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.
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 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.
