He's bitching about "bystanders" contributing towards his bullying by not helping him right after the glasses girl just tried helping him and he lied to her face. Do you want her to read your mind, you pathetic ingrate? "I was cursed with the personality of a slave," i.e. "I'm unwilling to take any action in my own life to better my situation and will instead blame others for not helping even when they try to." According to comments, he then threatens to kill everyone, including the girl that showed concern for him. I've seen some shitty revenge isekai MC, but holy.
