Perhaps he has found a new 'family' in his friends and comrades. They have shown him more love, support, and understanding than his biological family ever did. So, his focus has shifted completely away from his family, and he no longer cares for them as he has a new support system that he values more.
It could be due to some kind of misinformation. He might have been led to believe that his family didn't care about him, so in turn, he stopped caring about them. For example, if false rumors were spread about his family's intentions, it could warp his perception.
One way could be that Naruto has been repeatedly let down by Konoha. Maybe he was mistreated in the past, like being ostracized despite his efforts to protect the village. So in the fanfiction, he decides he's had enough and stops caring.
One plotline could be Naruto's journey to find out the truth about his family. He doesn't care about them initially, but as he uncovers secrets, his feelings start to change. Maybe he discovers that they had a noble reason for their actions that he misinterpreted.
Well, in such a fanfiction, it could make Naruto more self - reliant. Since his mother doesn't care, he might have to find strength within himself. He could become more determined to prove his worth not just to others, but also to himself.
Well, it could make the story much darker. Naruto's family, especially his parents, are important in his growth. If he doesn't care about them, his values would be completely different. He might become more self - centered and less likely to fight for the village. For example, his motivation to protect Konoha was partly because of his father's legacy. Without that family - driven motivation, he could turn into a character who is only after personal power.
One possible reason could be a misdirection in his goals. If in the fanfiction he is overly focused on proving himself to the village, he might think that family is a distraction. So, he starts to distance himself from his family to concentrate more on getting recognition from the village.
In the 'naruto doesn't care about his family fanfiction', Naruto may be depicted as having a cold attitude towards his family. He may not show any emotions when it comes to family matters. Unlike in the original where he was always longing for family love, here he might simply ignore his family members' needs. For instance, if his family was in danger, he might not rush to their aid as he would in the main series, instead focusing on his own personal achievements.
In the original series, Naruto is very forgiving and always tries to see the good in people. But in this fanfiction, he becomes more guarded and cynical. His lack of forgiveness towards his family might make him less trusting overall, not just towards them but also towards others. He may start to question relationships more and be less likely to give people second chances.
Well, not having a home in a fanfiction could make Naruto more independent. He'd have to rely solely on himself more. Maybe he'd become more distrustful of others at first because he has no safe place to call home. He'd be constantly on the move, which could make him a better fighter as he'd learn different survival skills.
In fanfiction where Naruto is hurt by his family, it can have a profound impact on his character development. Firstly, it could make him more withdrawn and distrustful. He might start to question his self - worth as family is supposed to be a source of love and support. For example, if his parents were alive but rejected him, he could become bitter. This could also lead to him being more self - reliant, relying less on others and more on his own strength. He may develop a tough exterior to hide his pain, but deep down, the hurt would still be there, influencing his actions and decisions in the story.
Well, without the curse mark, Sasuke may be less driven by the dark power it represents. He might focus more on his natural talents and training. This could lead to a more positive and self - reliant Sasuke, relying on his own skills rather than the boost from the curse mark.
