Some in Konoha could become angry with Naruto. They may feel that he has a duty to the village that he is shirking. They might start to spread negative rumors about him, saying that he has forgotten his roots. However, there could also be those in Konoha who understand Naruto's reasons, or at least try to. They might start to look for internal solutions to their problems instead of relying on Naruto.
Konoha might be in shock at first. They have always relied on Naruto to some extent, and his refusal to help is completely unexpected.
Maybe he has some personal grudges against the village. For example, he might have felt betrayed by the village in the past and that made him reluctant to offer help.
It could also lead to new alliances. Other villages might see Naruto's stance and try to form alliances with him, seeing an opportunity to weaken Konoha. This would then put Konoha in a more precarious position and force them to reevaluate their relationships with other villages.
Well, it completely flips the idea that Naruto is always loyal to Konoha. In the original story, Naruto's main goal was to protect the village. Here, his refusal makes Konoha vulnerable and forces the other characters to re - evaluate their relationship with Naruto and also their own role in protecting the village.
He would probably be very angry. Naruto has always been a free - spirited person, and being experimented on against his will would be a huge violation of his rights. He might initially try to resist physically, but as the situation gets more complex, he could start to plot his escape and revenge.
At first, Naruto is likely to be heartbroken. Konoha has been his home, and he has always longed for acceptance from the villagers. So being abandoned would be a huge blow to him.
The story could progress with Konoha facing a great threat without Naruto's help. The village might initially struggle to find a replacement for Naruto's power. This could lead to a sense of panic among the villagers and the leadership. Some might start to regret their past actions towards Naruto.
Naruto might initially try to reason with those who betrayed him. He would want to understand why they did it. But if they refuse to listen or continue to be hostile, he would start to distance himself from Konoha. He could become a lone wolf, using his skills and power to survive on his own while still trying to figure out how to clear his name and get revenge if necessary. He would also likely feel a sense of betrayal towards the friends he thought he had in Konoha.
It could be that Konoha wants Naruto to use his influence to bring peace among different clans. Naruto is well - liked and respected, and his words might carry a lot of weight.
Well, in some fanfictions, Naruto might outsmart Konoha by using his unique knowledge of the village's secrets that others don't know. For example, he could use his understanding of the old tunnels under Konoha to his advantage in a situation where he needs to escape or gain an upper hand in a conflict.
Perhaps Naruto has been pushed too far by the villagers' continuous mistreatment. Even though he has saved them multiple times, they still show hostility or indifference towards him. So, in the fanfiction, he decides not to help Konoha anymore as a form of self - protection and to break free from this one - sided relationship.
