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.
In the context of this fanfiction, Naruto's family might banish him because they don't fully understand his 'godlike' powers. They see the surface level of his new strength and assume the worst. Maybe they think he has been corrupted by some unknown force. Also, it could be related to power politics within the family. Some members might see Naruto's power as a threat to their own position and influence, and so they convince the rest of the family to banish him to safeguard their own interests.
He might be angry at first. Naruto has always been a character with strong emotions, and being abandoned would surely trigger his temper.
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.
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.
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 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.
It could also be due to some family curse or prophecy. In the Naruto universe, there are often strange powers and curses. Maybe there was a prophecy that said Naruto's family had to keep their distance from him to protect him from some greater evil. So, they chose to neglect him in order to keep him safe, even if it was a difficult choice.
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.
