Of course, a kill is still a kill. However, now that you've mentioned it, Sangwoo does have that kind of fucked up mentality, killing people who he thinks is vile, just like in death note. Even Seungbae is fucked up if you assess his "sense of justice". In the end, it's all about choosing the lesser evil, but it's still evil.
I hope they're gonna kill Bum's uncle. Btw...what if from now they're gonna kill only bad people?
