Hi did you forget the entire backstory of he literally beat this kid up nearly every single day and used his powers to burn others and cause them physically bodily harm? There is a world of difference between someone who trolls on the internet and someone with proven intent and capability to hurt others, that does it regularly. Violence escalates. Someone who carries guns everywhere in his fists with a history of violence and interest in someone else’s death claims they are not about to murder someone.
I cannot in my right mind understand how anyone can trust someone with a history of violence and commiting violence and uncontrollable violent outbursts and interest in someone’s death with the ability to cause that death. Bakugo blames everyone else for everything and if someone died he would call it an accident. An entitled asshole with a passion for violence and the ability to commit that violence and a history of violence. That is literally the profile of murderers. Bakugo is the type of person who would kill someone. He proved it time and time again, he has the anger to do it and the ability to do it and he threatens it constantly. There is a huge difference between a bully and a bully with a gun and a history of violence. And when that bully points the gun at someone and then chases their target down with it.
