Theory: Why did Sangwoo made Yoon kill that guy?
This is a theory that had come to my mind lately;
This theory is based off the though that Sangwoo is very aware of the fact that he is a killer and that these actions will mark him for the rest of his life. Doesn’t sound very surprising so far, does it? But let’s assume there is still a part in Sangwoo that is human, weak or vulnerable- we saw a glace of this side of him when he talked with Yoon about their pasts. We leaned that he had an abusive father and asked Yoon even before if his dad was the reason he cut his wrists.
I guess he asked Yoon not only because he was curious but because he wanted to get to know someone with a similar, abusive childhood, someone he can relate to.
And at some part, Yoon was that person who shared the experience of violence in his childhood with him. Maybe Sangwoo realized that he found a person he can relate to, that’s why he was so gentle with Yoon in the following chapter.
Already having a guess where I’m gonna go? Let’s take a look at the scene when that guy S. met in the gay bar, was killed. Here, it’s obvious that S. never intended to let Yoon die, even if he betrayed him during that card game (maybe to mess with him or to test his trust).
So my theory on why I think S. brought that guy home in the first place and made Yoon ‘commit a murder’ ; to make him and Yoon equal.
Sangwoo is a serial killer. As far as we know, he killed 3 persons- maybe even more. Contradicting to Yoon who maybe is a obsessive stalker but innocent in the regard of murder.
So in order to close this gap and make them able to fully relate to each other, Sangwoo made Yoon do this.
It’s only a theory of mine so let me know what you think but please note that I know this is a fucked up way of thinking.
I don’t want to defend Sangwoo for his actions, I just try to find the motives behind his actions.
