In episode 5, the frontman discovers some of his underlings have been helping Dr. Byeong-ki cheat in the game in return for his help harvesting dead contestants' organs, an operation he doesn't appreciate, as it supposedly breaks the most important rule of the game. "Whether you sell the dead body's organs, or eat them, or whatever, I don't give a damn," he exclaims before killing his underlings and the doctor. "You ruined the most important aspect of this place: equality. Everyone is equal when they play this game. Here every player gets to play a fair game under the same conditions. These players suffered from inequality and discrimination out in the world, and we're giving them one last chance to fight fair and win. But you broke that principle."
That's all great — if you can ignore everything else that goes down throughout the show. First, the puppeteers of the game let the contestants kill one another in all-out brawls, which isn't exactly fair to those who are elderly or not physically strong. Then there's the Oh Il-Nam factor. By the end of the season, we learn the unassuming older man is actually the affluent mastermind behind the game, which means he uses his influence to get as far as he does in the game and to evade death even though he technically loses his game of marbles. He also favours Seong Gi-hun throughout the games, ultimately faking dementia to let his Ggangbu win and escape death as well. How is that fair to the other players?
