It can also break characters' spirits. Consider Sasuke in a fanfic where he endures continuous cruel acts. He could become completely desolate and lose all hope, which is different from his complex and somewhat hopeful character in the original story.
In some Naruto fanfictions, a cruel act could be Orochimaru performing even more inhumane experiments on his subjects. He might use innocent villagers or captured ninja in ways that are more extreme than in the original story.
Well, in such fanfictions, Naruto's stupidity might make some characters more protective of him. For example, Sasuke could be more annoyed at first but gradually become more concerned as he realizes Naruto's good heart beneath the 'stupid' actions. And Sakura might scold him more often, but still care for him in a sisterly way. It can create some interesting dynamics in their friendships.
In some 'naruto acts cruel' fanfictions, Naruto might be depicted as being overly harsh in battle. For example, instead of showing his usual mercy, he could be written to use excessive force on opponents who are already defeated. This could be a way for the author to explore a darker side of Naruto's character, perhaps influenced by some extreme circumstances in the fan - created plot.
It could have a mixed impact. Some characters may be intimidated. Naruto's usual friendly and boisterous nature is replaced with Zabuza - like traits. Those who were close to him, like Iruka, would be worried. They would try to reach out to him to understand why he has changed. His relationships with the villagers could also take a hit. Since Zabuza was an outsider and a bit of a threat in their eyes, Naruto acting like him might make the villagers less trusting. However, some of the more battle - hungry ninjas in the village might see him as a stronger and more interesting ally now.
Sakura would be worried sick. She'd try to figure out what happened to Naruto to make him act this way. She might try to talk to him, use her medical ninjutsu to check if he's under some kind of genjutsu or has some other problem. She'd be very vocal about her concerns and would try to get the other villagers to help bring Naruto back to his normal self.
They can cause a lot of emotional damage. For instance, if a main character like Naruto has a 'bad mother' in the fanfiction, it might make him more distrustful or angry. It could also slow down his growth as a ninja because he's dealing with so much emotional baggage from his mother's actions. Maybe he starts to doubt his own abilities because of how she treated him.
Acts of violence based on true story often lead to changes in laws and policies. After a school shooting, for example, there might be new gun control regulations or enhanced security measures in schools. Society tries to prevent similar violence from happening again. Also, it can bring about social movements. The #MeToo movement, which was sparked by real - life accounts of sexual harassment and assault, has led to a huge shift in how society views and deals with such issues. It has empowered victims to come forward and has made workplaces and other institutions more accountable.
It can have a huge impact on the plot. Since Minato was known for his speed and intelligence, if Naruto acts like him, he would be more cautious and calculated. This could mean that he avoids some of the dangerous situations he got into in the original story. It might also influence how he deals with the Akatsuki. Instead of charging in head - first, he would plan more, which could change the whole dynamic of those confrontations.
The other Konoha ninjas would be quite shocked. The Hokage, whoever it is at that time, would see Naruto's change as a potential threat to the village's stability. They would likely keep a close eye on him and try to figure out what caused this transformation. Meanwhile, the younger generation of ninjas who looked up to Naruto would be confused and disappointed. They expected Naruto to be their role model of a kind - hearted and positive ninja, not someone acting like the feared Madara.
For Naruto, if there's 'Trouble in Time', he might be separated from his friends. For instance, if time is distorted, he could end up in a timeline where Sasuke never returned to Konoha. This would deeply affect Naruto as his goal was always to bring Sasuke back.
