On the other hand, it could also lead to some political consequences. Other villages might view the Hidden Leaf as more of a threat now that Naruto has shown such power. This could potentially strain relations with other villages, or it could also make some villages more eager to form alliances with the Hidden Leaf for protection.
The village might experience a huge boost in morale. Naruto killing Pain would be seen as a major victory, and the villagers would feel safer. They would look at Naruto as an even greater hero, which could lead to more trust and unity within the village.
The Hidden Leaf Village would be in deep mourning. Naruto is a hero to them, and his loss would be felt throughout the village. The villagers would feel a great sense of insecurity as Naruto was one of their main protectors. The morale of the ninja in the village would be low, but it could also lead to a new generation being inspired to become stronger in Naruto's memory.
One consequence could be that he leaves the village. He might go off on his own to find a new place where he feels accepted and can start anew.
One possible consequence could be chaos. Naruto was often seen as a symbol of hope and peace. His death at the hands of Madara would likely shatter the dreams of many characters. The villages might descend into fear and distrust again, and there could be a power vacuum that leads to wars between the different ninja villages.
One consequence could be a shift in the power balance in the ninja world. With Orochimaru gone, his followers might scatter or try to seek revenge. This could lead to new conflicts.
The most obvious change would be in the village's security. Naruto, as a ruler, would no doubt strengthen the village's defenses. He could form new alliances with other ninja villages, creating a united front against any potential threats. In terms of internal affairs, he might create more opportunities for the lower - class ninjas. Instead of only the powerful clans getting all the good missions, he could ensure a more equal distribution of tasks, which would improve the overall morale of the ninja population.
In fanfiction, when Naruto gets injured by Pain, it could also trigger some new powers or abilities within Naruto. Maybe the injury acts as a catalyst for him to tap into a deeper level of the Nine - Tails' chakra. His injury might also make the other villages more aware of the threat that Pain poses. They could decide to form alliances with Konoha in order to deal with the Akatsuki as a whole. This would change the political landscape in the Naruto world.
One consequence could be a shift in the power balance among the ninja villages. Since Orochimaru was a powerful and feared figure, his death might cause some chaos as his former allies or subordinates try to either avenge him or claim his resources. For example, some of his secret labs and experiments might be up for grabs, leading to potential conflicts.
A plot could involve the Leaf Village betraying Naruto when a powerful and ancient curse is placed on him that makes him seem like a mind - controlled puppet of a great evil. The village, in its panic, decides to take preemptive action against Naruto without fully investigating. This could lead to Naruto having to fight not only the external forces that are trying to use the situation to their advantage but also his own former comrades from the Leaf Village who are now hunting him down.
It could be due to a prophecy misinterpretation. Suppose there is a prophecy that Naruto misinterprets as the Leaf Village needing to be destroyed for the greater good. Or perhaps he is tricked by a very cunning enemy who convinces him that the Leaf Village is the root of all the problems in the ninja world.
One consequence could be that Naruto leaves the village. He might go on a journey alone, seeking a new purpose away from the place that has caused him so much pain. This would be a major change from his original story where he was so attached to the village.
