Both seem like they would have similar characteristics. But that's not the case. For Haneul (if it's the younger brother, not the dead older brother we're talking about) Then you can see that he has characteristics of a Psychopath because they exhume a charming facade. Manipulating others with their charisma (which he does when he first gets to the school and with his...lover boy?) and can mimic what is deemed as normal. And basically knows what it could be doing is wrong, but just doesn't care. Now, a sociopath, Isn't so organized or polished with their demonar, that means they could be easily set off by something, nervous, aggited and quick to show their temper.Also they are more likely to get into trouble with society and are able to form attachments, unlike Psychopaths. So really, both brothers are most likely psychopaths, because they match those characteristics then Sociopaths. Wow sorry for this not so needed explanation but I just found it interesting when it's paired with this story.
a psychopath? why not a sociopath? his flashbacks make him seem like a normal kid I mean... honestly this whole comic makes so little sense and i still cant tell apart the characters xdd they all look the fucking same help me plzz
