The other ninja villages would be very cautious. They would see this as a sign that the internal balance of Konoha was disrupted. Some villages might try to take advantage of this situation. For example, they could start to make moves on Konoha's territory or resources, thinking that Konoha was weakened by this internal strife. However, some villages might also respect Naruto's decision if they understood the threat that Sasuke posed.
The ninja world as a whole would be divided. Ninja who had a connection with Sasuke, like his former teammates or friends from other villages, would be deeply saddened and might seek revenge. On the other hand, those who had seen the destruction Sasuke could cause might support Naruto. This would lead to a lot of tension and potential conflict within the ninja world. There would also be a shift in the power dynamics, as Sasuke was a very powerful ninja, and his death would leave a void that different parties would try to fill.
The village of Konoha would be in shock. Naruto is seen as a hero, but killing Sasuke, who was also a powerful and well - known ninja, would be a very controversial act. Some might support Naruto, believing he had no other choice for the greater good. Others would be angry and might even turn against him, thinking he could have found another way.
Many of Naruto's friends and allies would be filled with rage. Characters like Sasuke would probably seek immediate revenge on Kawaki. The other villages might also see this as a sign of instability in the Hidden Leaf and could either try to take advantage or offer help depending on their relationships with the Leaf. And the younger generation, like Boruto, would be deeply affected. He would have to deal with the loss of his father and might struggle with his own identity and purpose in a world without Naruto.
The villagers would likely be in shock. Naruto is a beloved figure, but killing his own son would be a very controversial act. Some might turn against Naruto, believing he has gone too far. Others might understand his reasons if they knew the full story, but still struggle with the morality of it.
The village of Konoha would be in chaos. Naruto was seen as a hero, and if his dark side kills Sasuke, it would shatter the trust of many. His friends like Sakura would be devastated. She might go on a revenge quest against Dark Naruto. The Uchiha clan, which Sasuke was part of, would also be in turmoil. They might see this as an act of aggression against their clan and seek justice.
The reaction would be one of shock. Naruto is a well - known figure in the ninja world, and many see him as a symbol of hope. His friends like Sakura and Sasuke would be devastated. Sakura, who has known Naruto for a long time, would likely be in disbelief and filled with anger towards Tsunade. Sasuke, depending on his state in the fanfic, might seek revenge.
Some in the ninja world would likely be shocked at first. The idea of Naruto and Sasuke having a son together goes against the traditional views of many. But those who are close to them, like their friends from Team 7, would probably be supportive. Kakashi, for example, might see it as a new step in the evolution of the ninja world's relationships. However, there would also be those who oppose it, especially from more conservative clans who might fear the implications of such an unorthodox union on their power structures.
Sakura would be devastated. She has always had deep feelings for Sasuke. She might initially be angry with Naruto, thinking that there could have been another way. But later, she might understand Naruto's difficult decision when she realizes the threat Sasuke posed.
At first, Sasuke might not believe it was Naruto's own will. He would try to find out if Naruto was under some sort of external influence. But if he found out that Naruto was fully responsible, Sasuke's reaction would be one of pure hatred. He would abandon all his previous beliefs and goals and make it his sole mission to destroy Naruto. He might also cut off all ties with the village that Naruto was protecting, seeing it as an accomplice in his sister's death.
The ninja world would be quite shocked at first. Since both Naruko and Sasuke are well - known figures. People would be curious about the baby's potential. Some might be worried if the baby inherits too much of Sasuke's darker side. But most would also be excited to see what kind of ninja the baby would become, given the powerful lineages of both parents.
Some might see it as an opportunity to get closer to understanding Tobi's motives. Hidden Leaf Village, Naruto's home, would be torn between trying to save him and having to protect themselves from him. The younger generation who looked up to Naruto would be heartbroken and confused, and the older shinobi would be worried about the future of the ninja world with Naruto in this new, dangerous state.
The Uchiha clan might be divided. Some might support Sasuke's actions if they also feel betrayed by Konoha in the past, like how the Uchiha were treated before the massacre. But others might oppose it, seeing the long - term consequences of destroying the village.
