I think he means the rest of the group when he says npc because he deleted their tapes so they are all on auto mode now.
I don't think glasses guy is bad... he was just super paranoid and pissed off that Doha had basically ditched the actual players for an NPC. Or at least I would be super frustrated.
So
When Bada saw Doha, He killed the “NPC”,
And in this chapter He said the abandoned house is good since “Another NPC” won’t come.
Is he referring to Seoungchan (glasses guy) and others?
Like now Doha decided not to team up with the group, rather he might be the killer himself? And ejected everyone cassettes, making them NPCs.
Then Bada won’t interact with other guys ? He even told Bada not to get close with others.
But you can see, aside from glasses guy, other are good guys that could give Bada a clue.
