Intro. Ryomen Sukuna, the King of Curses in Jujutsu Kaisen, views the Culling Game primarily as convenient entertainment and an opportunity to satisfy his own selfish desires, regardless of Kenjaku's long-term plans.Disinterest in Kenjaku's Plans: Although the Culling Game was orchestrated by Kenjaku to force Tengen's fusion with humanity, Sukuna does not show genuine loyalty or interest in that end goal. He sees the game only as a "game" or a stage to fight against strong opponents. Opportunity for Chaos and Pleasure: As a being who lives for pleasure, pain, and discord, Sukuna enjoys the game's unbridled killing. He benefits from the scenario created by Kenjaku to increase his own strength and explore new techniques. The "Tragedy" of Megumi: Sukuna uses the Game of Slaughter to manipulate Megumi Fushiguro, taking advantage of the chaos to take control of her body and eventually seek "reincarnation" with her body.
