This shouldnt bother you coz that's how his character is written. He is a cold blooded killer. No need for a sappy backstory for him to be one. Not all psychopaths, serial killers etc have traumatic , tragic or sad experiences. Sometimes they are just like that.
well yeah thats why i said he could just BE some kind of mentally ill but this is not the part that gets me, its the casualness??? idk it just doesnt Fit and im afraid i cant put it into words... to try my best tho, this isnt some fantasy/supernatural/apocalypse etc etc narrative where the context of murder would be better placed? i guess iykyk and if u dont then its not a big deal im sure some others get what i mean loll
something that has rlly bugged me throughout this whole thing is like... people take ilay killing people so casually, even his brother... and its like. he didnt have a traumatic backstory or abusive parents that would result in him being careless and unsympathetic towards killing right, so ok then maybe hes just antisocial or psychotic or smth.. but its just so odd to me idk . still love this manhwa but its just something thats bothered me for the longest time
