Maybe you can help me out, because I’m a little confused as to why Gong Yoo became a goblin in the first place. Maybe I didn’t understand it right, but he became a goblin because he had the blood of all the people he killed on his hands. But if that’s right, the entire army, and the people they were fighting would be goblins too wouldn’t they?

You’re asking the person who literally fast forwarded through the origin story under the assumption the important bits would be repeated as needed.

My sassy answer is he became a goblin because he’s the lead.
