I think he just doesn't care about dying cause teach is the first person he's ever "cared" about. We've seen that he doesn't care about death plenty already. Remember he sees everyone else as animals and puts teach on a pedestal. I can easily see him being really ok with dying at his hands if that's what he really wanted (which he doesn't ).










Thank you for the update
Bro , I haven't finished reading this yet but saw everyone crying in the comment section ... What happens in the recent chapter ? Is it happy ending or not !
