Hinata would be devastated. She has always had deep feelings for Naruto. She might lose all hope and become a shell of her former self. Also, Kakashi would feel a great sense of guilt. He was Naruto's teacher and protector in a way. He would probably question his own abilities and actions that led to this situation. And for the village as a whole, it would soon realize the mistake they made when they face new threats without Naruto to protect them.
Iruka would be heartbroken. He was one of the first people to truly accept Naruto. He might try to make the villagers see the error of their ways, but it would be too late. The other ninja in the village, like Shikamaru and Kiba, would also be in a state of disbelief. They have fought alongside Naruto and know his true nature. This event could lead to a split in the village, with some believing they did the right thing and others realizing the great loss they have caused. And it could also attract the attention of other villages, which might see this as a sign of weakness in Naruto's village and plan to attack.
In such a fanfic, the plot might involve Naruto finally realizing the unjust treatment he received from the villagers in his past. He could start by using his powerful ninja skills, which he has honed over the years. Maybe he begins with small acts of disruption, like causing minor chaos during village festivals. Then, as his revenge plan unfolds, he might target the village's infrastructure, such as disabling the security systems. However, this would likely be a complex story as Naruto also has friends in the village who would try to stop him and make him see reason.
Well, Sasuke would be furious. Naruto was his rival and also his friend. He would seek vengeance on the mob without a second thought. Shikamaru, on the other hand, would be more calculating. He would try to figure out how such a thing could happen and what the long - term consequences for the village would be.
His character could become darker. The once - cheerful and optimistic Naruto might turn cynical. He would start to question all the values he was taught about loyalty and friendship. For example, he might see his past friendships as a form of manipulation by the village. This new - found bitterness would be a major shift in his character.
Well, one way could be that the villagers' long - hidden fear and jealousy of Naruto's power finally boil over. Maybe they believe some false rumors that Naruto is about to destroy the village. So, in a fit of panic, they turn on him all at once and overpower him.
Well, in such a fanfic, there could be a lot of drama. It might lead to changes in the relationships between Naruto and other characters. There could be social and family issues as well, like how the news is received by their friends and families in the fanfic world.
A plot could revolve around the power vacuum left by Naruto. The Leaf Village is in disarray, and other villages start to make moves against it. Pain might realize that killing Naruto wasn't really what he wanted in the long run, as it led to more instability. Or maybe a character who was in the background in the original story steps up to try and fill Naruto's shoes. They struggle to gain the respect and power that Naruto had, while also dealing with the grief of his loss.
In a fanfic where Naruto gets killed by Pain, it's a dark turn of events. The story would then likely focus on how the remaining characters cope. For example, Kakashi might feel a great sense of guilt for not being able to protect Naruto. Hinata would be heartbroken. Moreover, the Nine - Tails would be left without a host, which could also lead to all sorts of problems. The ninja world would lose its most prominent symbol of perseverance and friendship, and it would be a very different world from the one we know in the original Naruto story.
Well, it could lead to chaos in the Hidden Leaf. His friends like Sasuke might go on a vengeful rampage. They would be filled with rage and guilt, thinking they could have prevented it. The village would also be in turmoil, as Naruto was their hero and a symbol of hope.
It could be an old - fashioned village elder who has always been against Naruto. They might see him as a threat to the traditional way of life in the village and so start spreading rumors that lead to the villagers turning on him.
One possible plotline could be that the villagers, out of long - held fear and jealousy of Naruto's growing power, band together in a mob. They might ambush Naruto when he is least expecting it, perhaps on his way back from a mission. Another could be that they are influenced by a powerful and evil - minded individual who manipulates them into believing Naruto is a threat to their safety.
