He might have a stronger sense of justice. Because he has been through so much pain and neglect, he doesn't want others to suffer the same. So he is more likely to stand up for the weak and fight against injustice. He has a deep - seated understanding of what it's like to be alone and picked on, and this fuels his desire to create a better world for everyone, especially those who are also neglected or oppressed.
It could be due to his unique connection with the nine - tailed fox. Since his parents are not there to guide him, he has to figure out how to coexist with the fox on his own. In this process, he might accidentally discover some hidden powers within himself. Maybe the nine - tailed fox, seeing Naruto's loneliness and determination, decides to share some of its power with him, which gradually makes Naruto godlike.
One possible reason could be that they are too involved in their own shinobi duties. The world of ninjas is full of dangerous missions, and they might be constantly away on important tasks, leaving Naruto feeling neglected.
Naruto might try to seek attention elsewhere. He could focus on his training more intently. By pouring his energy into becoming stronger, he distracts himself from the pain of parental neglect. Also, his friends could play a crucial role. Their friendship might give him the sense of family and belonging that he lacks at home.
One reason could be that his siblings have some special abilities or talents that overshadow Naruto. In the ninja world, those with unique powers often get more attention. So, if his siblings possess something extraordinary, Naruto might be pushed to the side.
He might try to prove himself. Naruto has always been a determined character. He could focus on his ninja training more intently, aiming to show everyone his worth despite being neglected. Maybe he'd also start to distance himself a bit from his family situation and form closer bonds with his friends like Sasuke and Sakura, who might understand and support him through this tough time.
Well, Naruto has always been a fighter. In this situation, he might start to explore his own unique abilities more deeply. He could go on solo missions to prove his capabilities. Also, he might look for a mentor figure other than those in his immediate family. For example, he could turn to Kakashi for more guidance and training. By doing these things, he gradually shows that he is not someone to be neglected.
He might try to prove himself. Naruto has always been a determined character. So, he would likely focus on his training more, aiming to show his worth to those who neglect him. For example, he could strive to become a stronger ninja faster than his siblings, in the hope that his efforts would be noticed and the neglect would stop.
He might focus on his training more. By pouring all his energy into getting stronger, he can distract himself from the pain of family neglect. For example, he could spend long hours practicing new jutsu or improving his physical abilities.
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.
Maybe he's been influenced by someone who has a different view of heritage. For example, if he meets a character who believes that one should create their own identity rather than relying on heritage, Naruto could be swayed. Another possibility is that he has some sort of resentment towards his heritage. Perhaps there are things in his family's past or in the traditions associated with his heritage that he doesn't agree with or is ashamed of.
