Throughout every season of Squid Game, I observed a deeply unsettling aspect of human nature embedded in the plot and characters—sadism. Squid Game by Hwang Dong-hyuk, released in three seasons over three to four years, is a survival horror series. Dystopic in nature, it revolves around a children's game, wherein participants gamble their lives in pursuit of a massive cash prize. The latest season not only brings the storylines of the previous seasons to a dramatic culmination, but also vividly projects the escalation of brutality and the manipulation of human nature. It presents a stark portrayal of the sadistic pleasure those orchestrating the game derive from witnessing the players' suffering.
