Miss and mister edgies in the comment section bashing a reincarnated modern person with modern morals for not being cruel and sadistic enough—either you people never saw a real execution, even footage, or are frequent visitors to goreleak or some shit. Primal instincts aren't there for no reason.
I'm surprised that the father didn't consider taking the MC to the battle in order to be further exposed to death of others.
Hopefully he won't die during this conflict, I don't think the MC is ready for that yet.
It's funny his dad expects that out of him but has never trained him to do so. You don't expect someone to be ok with death and killing from the get go, unless they're a psycho.
