Some family members might try to secretly rehabilitate Naruto. They would hope to bring him back to his senses and make him realize the error of his ways. However, there could also be those in the family who are so ashamed that they would rather forget about Naruto altogether and try to erase his existence from the family's history.
His father might be extremely disappointed. As a former Hokage, he would have expected Naruto to uphold the family's honor. His mother would probably be heartbroken, having always believed in Naruto's good nature.
Well, in some fanfictions, a 'godlike' Naruto might become overconfident. His newfound power could make him act without considering his family's values or traditions. For example, he might use extreme and unethical means to achieve his goals, which his family would not approve of, thus dishonoring them.
It could also be due to some external influence. Perhaps an enemy manipulated Naruto's mind in the fanfiction, making him see his family in a negative light. This enemy might have used some form of mind - control or false memories to turn Naruto against his family.
One possible reason could be that his newfound 'godlike' powers make his family feel estranged. They might not understand his sudden transformation and the magnitude of his power, which creates a sense of fear or discomfort, leading them to ignore him.
One possible plot could be Naruto's struggle to rise above the abuse. He might discover his godlike powers gradually while facing the emotional and physical abuse from his family. He could start to form his own support network outside the family, like with his friends from the ninja academy, and use his newfound powers to prove his worth not only to his family but also to the whole village.
Well, one possibility is that Naruto, in his godlike state, might feel that his family's expectations or their way of life is holding him back from achieving some greater good. Maybe he has a different vision for the ninja world that his family doesn't understand or support, so he rejects them to pursue that vision on his own.
One reason could be that Naruto has been through a lot of hardships related to his family in the fanfic. Maybe they didn't support his growth to this godlike state, or they tried to use his power for their own gain. For example, if his family had always been jealous of his potential and when he finally reached this ultimate power, he realized their true nature and decided to cut ties.
Naruto might end up feeling extremely lonely. His family has always been an important part of his life. Without their support and presence, he could become depressed or start making even more reckless decisions. Also, if his family tries to search for him, they could get into danger themselves in the process, which would be an unintended consequence of his hiding.
He could become stronger on his own. Away from his family, he'll have to rely solely on himself. This self - reliance might push him to train harder and unlock even more of his 'godlike' powers. For instance, he might find new mentors or training methods that his family would not have allowed.
One possible reason could be a misunderstanding. Maybe Naruto overheard something his family said that he misinterpreted as them not loving or believing in him. For example, if he heard them talking about his wild nature or his past mistakes in a way that he took the wrong way.
Maybe there are secrets in the family. For example, his parents might be involved in some dangerous and secretive missions that require them to keep their distance from Naruto to protect him, but Naruto misinterprets it as neglect.
