In the comics, it's a complex situation. Different storylines might have different outcomes, but as of the common ones, no one has directly killed Homelander.
Well, Homelander is usually depicted with extraordinary powers in comic vine. A train, on the other hand, is just a mode of transportation. So, Homelander has the edge in terms of power.
In this kind of fanfiction, a likely consequence is that it changes the whole dynamic of the story. Their classmates might take sides. Some might side with Izuku out of sympathy, while others might try to understand Bakugou's actions. It could also lead to changes in the school's view on Bakugou, perhaps implementing stricter rules or counseling to prevent such incidents in the future.
One common theme is self - doubt. Naruto may doubt his worth as a ninja or a friend, feeling like he has let everyone down. Another theme is the burden of his past. All the hardships he has faced can pile up and seem overwhelming, pushing him towards self - destruction.
I'm not sure if there is a specific novel with exactly this plot. It could be a very niche or even a fictional concept created for a particular discussion. There are many vampire - related novels in the world of literature, but this specific combination seems rather unique.
One possible reason could be a misunderstanding during a battle. Maybe there was some sort of jutsu misfire or misinterpretation of an attack. For example, if Kiba was using a new and powerful technique that Naruto didn't recognize, Naruto might instinctively go all - out in self - defense, nearly killing Kiba.
One popular 'naruto almost kills himself' fanfiction might be 'The Brink of Despair'. In it, Naruto faces extreme emotional turmoil after a major loss and comes dangerously close to self - harm. However, his friends' memories and his unwavering will to protect the village eventually pull him back from the edge.
Naruto could try to talk her out of it. He is a firm believer in the power of friendship and words. So, he would likely use his words to try and break whatever spell or wrong idea is in Sakura's head that made her want to kill him.
One possible reason could be a misunderstanding. Maybe Sasuke is framed for something really bad, and Naruto, in his anger and sense of justice, lashes out without knowing the truth. For example, if there's a false rumor that Sasuke has attacked the village again, Naruto might be quick to act.
