Naruto's lack of trust in his family might make him more cynical in the fanfiction. He may start to view relationships in general with suspicion. For example, he might have a harder time opening up to new people or believing in their good intentions. However, this could also be a phase that he grows out of as the story progresses. If he overcomes this lack of trust, it could be a major step in his character development towards becoming a more well - rounded person.
This lack of trust could also fuel his determination. He may feel the need to prove himself without the help of his family. So, he'll strive harder to achieve his goals. But at the same time, it might also create an inner conflict within him. He might secretly long for a better relationship with his family while still being unable to trust them, and this internal struggle can add depth to his character development.
It changes the direction of the story significantly. Usually, Team 7 is a united front, but with Naruto's lack of trust, it becomes a more complex and often darker narrative. There could be more internal battles within the team rather than just fighting external enemies. This can also lead to alliances being formed in different ways. For example, Naruto might form temporary alliances with other characters outside of Team 7 to achieve his goals or to protect himself from what he perceives as threats from his own team.
It would strain their relationship a great deal. Naruto might avoid Kakashi, not seek his advice or training as he used to. This could lead to Naruto making more mistakes in his development as a ninja because Kakashi has a lot of knowledge and experience to offer.
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.
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.
Well, it can make Naruto a loner in fanfiction. He might develop a 'me - against - the - world' attitude. Since he doesn't have the support of a family, he could become overly independent, not relying on anyone for help. This may also affect his relationships with his teachers. They might find it harder to reach out to him because of the emotional wall he has built up due to the abandonment. And in battle, he could be more reckless, feeling like he has nothing to lose.
His relationships would become very strained. Friends might feel hurt that he doesn't trust them, which could lead to arguments and distance. For instance, Hermione might be constantly trying to prove herself to him, but he still remains skeptical.
In the fanfiction, Harry's lack of trust could lead to a lot of misunderstandings. His friends may misinterpret his caution as a lack of care for them. It could also isolate him. People might start to avoid him if they feel he is always doubting them. This isolation could then further fuel his lack of trust as he has fewer positive interactions with others, creating a downward spiral in his relationships.
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.
