Nam-gyu is still somewhat mentally disturbed. Like Thanos, he doesn’t care about using other people to his advantage and sees them as disposable. He also shares Thanos' vengeful nature, and sees any comrade who opposes him as a traitor. He can also act very rudely towards others people and displays crude and inappropriate behavior. However, he also appeared to be a coward as he heavily relied on taking the pills to suppress his fears in the games.
