Spoiler:
He did kill people lol. Several in fact. And let's nor forget the fact that, if you get someone else to do the killing for you, the justice system says that you are just as guilty if not more so than the actual killer. (There have been cases where the people who hired someone to kill for them got the death penalty while the actual killer got away with just jail time.)
But I agree with the fact that he is an interesting character. Poor Kirin doesn't even know how much he is being manipulated and toyed with. He is in for a rude awakening if he ever finds out.
oooh interesting. I agree with you completely actually. And yes, Kirin's definitely being manipulated which is why I keep hoping he secretly has a dark side too but it seems unlikely haha.
But I actually think Kang Moo still fits the bill of an anti hero even if he did kill people. (ie: hannibal lecter, dexter, villanelle etc) It's mostly because he's currently standing on the right side of justice and punishing the rapists. He's also the one who is actively moving the pieces of the story instead of our main character kirin.
Kang moo is such an interesting and complex character. I almost feel like he's the actual main character here lol, especially considering how he never actually killed a person. He could easily be the anti-hero of a tv series or movie.
