One possible reason could be that the family feels wronged by Konoha's political decisions. Maybe they were unjustly targeted or their clan was persecuted in some way by Konoha's leadership. For example, if their clan was blamed for something they didn't do and faced severe sanctions as a result.
The story might also develop with a key member of the Naruto family infiltrating Konoha's inner circle. This person could gather intelligence and try to undermine Konoha from within. For instance, by spreading false rumors or causing internal strife among the different ninja teams. As the story progresses, there would be a build - up of tension between the family and Konoha until a full - scale battle or confrontation is inevitable.
One possible reason could be a sense of betrayal. Maybe Naruto discovers some dark secrets about Konoha that make him feel deceived. For example, if he found out that the village had been using him all along without truly caring for his well - being.
The story could start with Naruto slowly distancing himself from Konoha. He might start by not taking on any more missions for the village and instead focus on building his own power. For example, he could seek out new jutsu training from other places or with rogue ninjas who oppose Konoha.
Naruto would probably be conflicted. On one hand, he has a deep love for Konoha, his home. But on the other hand, he might have been hurt by the past events that led to his departure. He could initially be hesitant, but eventually be swayed by the thought of seeing his friends again.
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.
Sasuke could be one of the characters to support Naruto. Given their complex relationship and Sasuke's own issues with Konoha in the past, he might see Naruto's cause as just. Another one could be Jiraiya. If he were alive and found out about the real reasons behind Naruto's revenge, he might side with Naruto as he always cared for him deeply. Also, some of the outcast ninja within Konoha, like those who have been discriminated against because of their bloodline or lack of skills, might support Naruto as they also have grudges against the village system.
Well, in some 'Naruto revenge on Konoha fanfiction', Naruto may gain a super - powerful and dark - sided ability. He then decides to use this ability to take revenge on Konoha. Maybe he starts by targeting the shinobi who once bullied him, like Sasuke did in the original story but in a more extreme way. He could also aim to take down the village's hierarchical system that he believes is corrupt. He might use his knowledge of Konoha's weaknesses, such as the location of its secret bases and the chakra patterns of its important shinobi, to his advantage in his revenge plan.
Another plot development might be that Konoha asks Naruto to train the next generation of ninjas. Naruto, being the hero of the village, has a lot of skills and knowledge to pass on. He might face challenges in training the newbies, like dealing with their different personalities and abilities, but in the end, he manages to create a strong new generation for Konoha.
One possibility is that Naruto would return with newfound strength and wisdom. He might have learned unique techniques during his time away. Konoha could welcome him with open arms and immediately put his skills to use in protecting the village. For example, he could train the new generation of ninja, sharing his experiences from his travels.
