Mahito

Mahito is an immature and sadistic cursed spirit who enjoys toying with human emotions. He believes he was born from human transgressions and considers himself the manifestation of humans' hatred of each other. As such, Mahito supports human extermination and deems cursed spirits to be the true rulers of the world. Unlike his ally Jogo, who is short-tempered and arrogant, Mahito can remain relatively calm and playful upon confrontation with an enemy. Even so, they agree on the same goals for the future of their kind. He has a genuine friendship with the other curses, as he scolds Pseudo-Geto for putting Jogo in danger, protects Hanami from Haruta, and wants to avoid fighting with Jogo in Shibuya. Mahito is also very philosophical when it comes to the concept of souls. He believes the human soul existed before the body and is intrigued by its nature. His cursed technique is derived from this obsession, and he uses it to experiment on human victims to gain further knowledge. Mahito has no sympathy for humans and appears to place little value even on his own life. He is devoted to the cause, believing that reviving Sukuna is more important than his own well-being. As long as cursed spirits eventually reign supreme, Mahito doesn't care if he's there to see it. Possibly due to the nature of his birth, Mahito is adept at psychological manipulation. He preys on human hatred, sorrow, and insecurities to direct people to accommodate his goals to the point where his victims go against any common sense. After indirectly causing the death of Junpei's mother by placing Sukuna's finger in her house, he convinces her son that the one who did it was Shota Ito, which, in turn, drives Junpei to become a curse user to avenge his mom. Mahito manipulates Junpei so thoroughly that the boy never considers Mahito evil, even after seeing his experiments in the sewer. Junpei only realizes Mahito's twisted nature when it's too late, moments before Mahito disfigures his body.
