@Loud @Loud He didn't become a hero on his own will. He was interdimentionally kidnapped, told the only way to return home was to defeat the demon king and go to war(which doesn't leave him with any choice so it's basically forced labor), and throwing a child who was still growing up into war and forcing the child to commit multiple murders so as to fight for an unknown cause and a war had nothing to do with him does a number on your mental(mind you he's still developing so his mental state is still fragile). Then in the course of the war he witnessed his companions deaths and still moved on. To this point his mental is completely broken, the only thing holding him together is the thought of reuniting with his family and friends and going back home. And when he finally does, he has no home to return to, his parents are dead, the relatives want nothing to do with him, school expelled him, his friends left him, basically the world that he desperately wanted to go back to no longer exists, only a facade in his eyes. So he has to tear it down and bring it up to his reality so that they can see from his point of view.

@No_one some of them had a life and family back home. It was basically an interdimentional kidnapping, forced labor, no home to return to.

@Seb yo chill, it's only the 4th chapter
