Man, Hirata has no redeeming part of him.

I wanted to think that way but Sensei treasures all of her characters, good or bad. The backstory in this chapter is not complete, we still don't know who Hirata is before he was in the Yakuza. If Sensei explores more about Hirata, she can make him more pitiable. Of course, I am in no way saying his sins are ever forgivable. He fucking killed someone by his own hands but at least his actions and personality would have a reason not just simply a psychopath, can't say he's a sociopath since we just found out he doesn't have a conscience.
