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.
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.
Maybe in the fanfic, Itachi has done something that goes against Sakura's beliefs or values. For example, he might have made a decision that put her friends in danger.
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.
It could be that the gay man reached his limit of tolerance with the partner's self-centered behavior. The constant lack of understanding and empathy might have pushed him over the edge.
Well, there could be various reasons. Maybe there was a deep-seated family conflict that escalated beyond control, or Jeffrey might have been influenced by external factors like drugs or a traumatic event.
It could be that the Moore was mentally unstable or influenced by external factors that led him to commit such a horrifying act. There might have been financial problems, jealousy, or a history of abuse that culminated in this tragic event.
