In many fanfictions, the scenario of Naruto and Itachi killing the Uchiha clan is a very interesting but also controversial topic. One aspect could be the change in Naruto's character. Usually, Naruto stands for justice and protecting others. If he were involved in such a massacre, it would be a huge deviation from his original character. Maybe in the fanfiction, there could be some extreme situations that force him to do so, like being mind - controlled or having some false information.
One possible motive could be mind control. Maybe an enemy used a powerful genjutsu on Naruto, forcing him to commit this heinous act against the Uchiha clan.
In some fanfictions, a possible motivation for Naruto could be to prevent a greater evil. Maybe he was tricked into believing that the Uchiha clan was about to start a war that would destroy the entire ninja world. So, he thought that by taking part in killing the clan, he could save more lives in the long run.
One possible plotline could be that Naruto is forced into a situation where he has to kill Itachi to protect the Hidden Leaf. Maybe Itachi is being controlled by some dark force and Naruto, with great reluctance, has to end his life to save the village and his friends.
Well, in some fanfictions, Naruto might start by finding suitable partners within the village. Since he is the last of his clan, he could look for women who are willing to carry on the Uzumaki bloodline. He may also use his influence as a hero to encourage others to support his clan - revival efforts, like getting the village to provide resources for the new Uzumaki generation.
In the game Imperial Dragon in the Sky, the way clans killed monsters and killed people to gain experience was different. Therefore, some people thought that killing monsters would give more experience than killing monsters.
Killing referred to directly defeating an enemy player or NPC to gain more experience than killing monsters. This was because players could directly obtain items and equipment from enemy players or NPCs during the killing process. These items and equipment could increase the player's combat strength and thus increase the player's experience gain efficiency.
On the other hand, the clan needed players to fight not only against enemy players or NPCs, but also other players. In the process of killing monsters, players needed to constantly improve their combat power and skills in order to successfully defeat their opponents and obtain more experience.
Although killing monsters and killing people could give experience, killing people gave more experience. This was because players could directly obtain items and equipment from enemy players or NPCs during the killing process to increase the efficiency of gaining experience.
In this fanfiction, Naruto could reject his clan because of the dark secrets or past actions of the clan. He is a character who values justice and friendship. If the clan has a history of wrongdoings that he discovers, he may not want to be associated with it. Also, Naruto has his own dreams and goals that might not fit within the framework of the clan. He has always been a bit of a rebel, and rejecting the clan could be his way of standing up for what he believes in.
One possible reason could be to seek greater power and training opportunities elsewhere. Maybe he feels restricted within his clan in terms of the type of jutsu he can learn or the level of training he can receive. So, he decides to leave to explore different ninja arts and grow stronger on his own terms.
A really interesting plot twist could be that Itachi fakes his death at Naruto's hands. He then secretly works behind the scenes to help Naruto defeat the real threats to the ninja world. This would completely change the dynamic of the story and add an element of mystery.
Yes, there are likely such fanfictions. Many fanfiction writers like to explore the idea of Itachi coming back to life with his memories intact. This allows for interesting character interactions, especially with Naruto. Itachi could use his wisdom and skills once again, and his relationship with Naruto could further develop in new and unexpected ways.
