Yes, there might be such fanfictions out there in the vast world of fan - created content. However, it's important to note that fanfictions can vary greatly in quality and adherence to the original spirit of the Naruto series.
One common theme is justice. Naruto seeking revenge is often seen as a way to right the wrongs done to him or his loved ones. It's about making the guilty pay for their actions.
The betrayal could lead to Naruto having trust issues not only with Sakura but also with others in the future. He might become more guarded and less likely to open up to people. For Sakura, if she comes to her senses later, she would have to face the enormity of what she has done. She would have to grovel for Naruto's forgiveness, but it would be a long and difficult road to regain his trust.
No, it is not ethical at all. Rape is a serious and extremely traumatic act, and writing fanfiction about it, especially in a non - educational or non - consensual context, is inappropriate and disrespectful to the characters and the readers. It promotes a negative and disturbing view of sexual violence.
In some fanfictions, it could be due to unrequited love. If Naruto has deep feelings for Sakura but she continuously rejects him in a cruel or thoughtless way, Naruto might feel angry enough to seek revenge. For example, she could publicly humiliate him for his feelings, which would hurt Naruto deeply and lead to thoughts of revenge. Another reason could be a misunderstanding. Suppose Sakura is misjudged by Naruto as having done something terrible when in fact she was innocent. But Naruto, in his ignorance, decides to take revenge. This can create a lot of drama and conflict in the fanfiction.
Naruto could initially be angry. He might think Sakura overreacted. But then, after a moment, he would probably realize his own mistake if there was one. He'd then try to play it off with a joke to ease the tension between them, like he always does in tough situations.
There's also 'Revenge of the Jinchuriki: Naruto's Path'. Here, Naruto's motivation for revenge could be related to the discrimination he faced due to being a Jinchuriki. He decides to show the world that he's not a tool but a powerful force. The fic might explore his growth as he battles against those who have underestimated and mistreated him.
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.
One common theme is betrayal. Naruto might feel that Konoha has betrayed him in some way, like hiding important information or not standing up for him when he needed it. This sense of betrayal then drives his revenge.
One possible story could be that Naruto discovers Sasuke has joined a dark organization that is planning to destroy Konoha. Naruto, filled with a sense of betrayal and duty, decides to take revenge. He trains harder than ever, mastering new jutsu. When they finally face off, Naruto uses his newfound power to defeat Sasuke without killing him, instead making him see the error of his ways.
