@coral but what ure not getting is that we have seen him acknowledge that he KNOWS he is doing harm and that what he's doing isn't good. he has acknowledged it and that's what separates him from psychopaths who are not fully aware of their wrongdoings. ofc he is still very deluded by it all but he has shown us that he acknowledges what he is doing is wrong and that's why what he does is so much worse and easier to blame him for. he is fully responsible for his own actions bc he KNOWS when he is doing most of it (obvs he has blow overs where he goes blind with violence) and that's why its perfectly fine to call him out on him for not doing better. he knows exactly what to say and do to make yoon listen and do as he says, the fact that he's capable of manipulation to the degree of the ppl around him (his "friends", police think he's kind, etc) as well is more than enough to clarify that he knows enough to know what he's doing is wrong. it's not like he's just like "oh no i don't know why ure afraid of me for killing that girl, i didn't know killing was bad 😦".
