Perhaps Naruto is blinded not just physically but also metaphorically by the villagers' actions. This could lead to a period of self - reflection for him. He might question his own beliefs and his desire to be accepted by the village. He could start to explore his own identity outside of the village's expectations. And as he grows in this self - discovery, he could also become a symbol of change within the village, inspiring others to look at things differently.
His character changes in terms of his trust. He was always eager to gain the villagers' trust before, but after being blinded by them, that trust is severely damaged. He may become more guarded and less likely to open up easily. Also, his sense of justice might be more intense. He could be more driven to fight for the rights of those who are wronged, since he has now been a victim himself. He might also develop a deeper sense of empathy for others who have suffered at the hands of the unjust.
One possible reason could be fear. The villagers might be afraid of Naruto because of the Nine - Tailed Fox sealed within him. They see him as a potential threat and lash out in their fear. Another reason could be jealousy. Naruto is a powerful ninja in the making, and some villagers, who are not as strong or talented, might take out their insecurities on him.
One possible plot development could be that his friends, like Sakura and Sasuke, come to take care of him. Sakura uses her medical skills to try and bring down his fever. Another could be Naruto having fever-induced dreams about his past, like his lonely days as a child. Maybe he even hallucinates about his parents. It could also lead to a situation where the village is in danger, but Naruto is too sick to help at first, creating a sense of tension and urgency among the other characters.
One possible plot development could be Naruto finding strength within himself. He might start to question why his parents would do such a thing and through that self - reflection, he could begin to discover his own worth. Maybe he'll meet a mentor figure who helps him see that his parents' actions don't define him.
One possible plot development could be Naruto's struggle to break free from Orochimaru's control. He might have to face his inner demons and find new sources of power within himself. Another could be his friends trying to rescue him and having to fight against Orochimaru's minions. Maybe Naruto under Orochimaru's control is used to target the Hidden Leaf Village, creating a huge conflict.
One possible plot development could be Naruto developing new and unexpected powers as a result of the experiments. For example, he might gain the ability to use some of Madara's unique jutsu in a different way. Another could be Naruto's friends trying to rescue him and in the process learning more about Madara's true motives and the nature of the experiments. Maybe Naruto also has to struggle with his own identity as he is changed by the experiments.
One possible plot development could be Naruto's friends rallying around him. They might seek out medical help, like Sakura using her skills to stabilize him at first. Then, they could start planning revenge against Pain. Another could be Naruto having some sort of vision during his injury, perhaps about his parents or a new power he could unlock to defeat Pain in the future. And, his sensei, Kakashi, could take on a more protective role over him as he recovers.
The plot could also explore how Naruto's identity as Nagato's son affects the Akatsuki. Maybe some members of the Akatsuki would try to recruit him or use him for their own purposes. On the other hand, Naruto might try to reform the Akatsuki from within. His connection to Nagato could also lead to a different resolution of the conflict between the ninja villages. Instead of just uniting the villages as in the original story, he could aim to create a more global peace based on Nagato's broader view of the world, which was not just limited to the ninja villages.
One possible plot development could be Naruto gaining new and extremely powerful abilities. For example, he might be able to use Kyuubi's chakra in more refined ways, like creating unique jutsu that combine his own skills with the raw power of the Kyuubi. This could make him nearly invincible in battles against his enemies. Another aspect could be his relationship with his friends and the village. With the new power, some might fear him while others try to understand and support him. It could also lead to Naruto having to face new and stronger foes who are attracted by his enhanced power.
One possible plot development could be Naruto growing up in isolation, constantly feeling the sting of being abandoned. He might develop a strong sense of self - reliance and a burning desire to prove himself to his family. Maybe he starts training secretly and becomes extremely powerful on his own. Then, when his siblings finally realize their mistake, Naruto has to decide whether to forgive them or hold a grudge.
