There's also 'The Bond of Enemies'. In this fanfic, Pain, after his defeat, is given a second chance at life by Naruto. It shows a really interesting dynamic as Pain tries to figure out his new place in the world with Naruto's influence. It has some great action scenes and emotional moments.
It could be about Naruto having some sort of connection to Pain. Maybe in this fanfiction, Naruto is somehow related to Pain in a way that wasn't in the original story, like being his son in an alternate universe. This could lead to a whole new set of storylines, with Naruto perhaps having to deal with the legacy of Pain while also following his own path as a ninja.
The moment when Naruto first realizes his feelings for Hinata during a kiss is often a great moment. It's like a light bulb going off in his head, and suddenly he sees Hinata in a whole new light.
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.
Obviously, Naruto would be one of the main characters as it's about him being the son of Pain. Pain himself would also be a crucial character, even if he might not be physically present all the time. And characters like Sasuke, Sakura, and Kakashi would still likely play important roles as they are Naruto's friends and mentors in the original story and would have to interact with Naruto in this new, changed scenario.
A fanfiction titled 'Naruto's Admiration for Pain' is also worth checking out. It focuses on Naruto's growing admiration for Pain's power and ideology. However, Naruto also tries to change Pain's more extreme views. The story is full of intense dialogues and Naruto's internal struggles.
Well, in the original Naruto story, Pain's actions are somewhat more straightforwardly presented as villainous. But in the fanfic, it might humanize Pain more. It could show his past traumas and how they led him to his extreme beliefs and actions.
Because I'm a reader of novels and have no background knowledge of any particular culture or faith. I can only provide objective facts and information. Whether or not it was an evil book depended on the specific cultural and religious background. I can only provide general knowledge and cannot make such a judgment.
Friendship is also a big theme. Since they start as enemies, fanfictions like to show how they can develop a deep friendship. They might start to understand each other's past traumas and find common ground, leading to a strong bond that was not present in the original story.
In this fanfic, it might also re - imagine the battles involving Pain. Instead of the battles being just about physical combat, it could explore the psychological warfare aspect more. Pain's abilities, like the Six Paths of Pain, could be used in more creative ways to create a more engaging and different story. It could also focus on how the other characters in Naruto try to understand and counter Pain's complex ideology while dealing with the destruction he causes.
