Well, it would also affect the relationships of other characters. For example, his friends in Konoha would either try to regain his trust or they might side with Konoha against him. This would add a whole new layer of complexity to the plot as characters are forced to take sides and deal with the consequences.
It might be due to hidden secrets. If there are dark secrets within Konoha that Naruto discovers in the fanfiction, such as a conspiracy that involves some of the higher - ups. This would make him lose trust in the village as a whole.
One possible reason could be miscommunication. Maybe Kakashi has been involved in some secret missions or decisions that Naruto doesn't understand, leading to a breakdown in trust. For example, if Kakashi made a call during a battle that put Naruto or his friends in danger without fully explaining it to Naruto later.
One possible reason could be past betrayals. Maybe he has been let down by people he thought were friends in the fanfiction world. For example, if someone he trusted shared his secrets which led to him getting into trouble.
One possible reason could be that Naruto has had some past experiences within the team that made him feel betrayed or let down. Maybe there was a mission where he thought his teammates didn't have his back. Another reason might be that there are secrets among the team members that Naruto has discovered, and these secrets make him question their loyalty. For example, if one of his teammates was hiding a connection to an enemy, Naruto would naturally start to lose trust.
His lack of trust could lead to a lot of misunderstandings. For instance, if someone tries to help him but he misinterprets it as a malicious act because of his distrust. This can create a cycle of more distrust as others start to feel frustrated with him.
It could be due to miscommunication. In the fanfiction, perhaps there were misunderstandings within the family. For example, Naruto might have overheard something that made him think his family didn't have his best interests at heart, but in reality, it was all a big mix - up. So, he gradually lost trust in them.
It could also be due to Sasuke's secrecy. If Sasuke is constantly hiding things from Naruto, like his real intentions or new powers he's acquired, Naruto would naturally start to feel that he can't trust him. Trust is built on honesty and openness, and if Sasuke is being cagey, Naruto's trust in him will fade.
One possible reason could be that Naruto feels betrayed by Konoha. Maybe he discovers some dark secrets about the village that make him lose faith in it. For example, if he finds out that the village elders were involved in unethical experiments or plots against his friends or family, he might not want to help.
It changes the dynamic between Naruto and the village. Since Sarutobi was an important figure in the village, Naruto's distrust can create a rift not just between them but also between Naruto and the traditional village values Sarutobi represented.
