What was Kenjaku actually trying to do?Fiction

In-universe lore. Claims are judged against the fiction's own canon, not the real world.

Kenjaku is the thousand-year-old brain that has worn one body after another across Jujutsu Kaisen, and almost everything readers know about his plan comes from his own mouth. This ledger separates what Kenjaku asserts about his goal from what other characters and the wider narrative actually confirm.

    • Tengen explains that Kenjaku wants to force the evolution of all the people of Japan.

[...] He has never considered taking over the bodies of Gojo and Toji. Gojo is an impossible option since he is unbeatable. Toji isn't impossible, but if Kenjaku was to take over Toji's body, there's a chance that Toji's Heavenly Restriction and Kenjaku's technique may clash.Jujutsu Kaisen Official Fanbook, pp. 74-75, quoted in the Kenjaku article - Jujutsu Kaisen Wiki Word of God

  • The reading that the figure in Geto's body was really Geto, back for revenge over a past fallout with Gojo and the school, does not hold: the body is controlled by Kenjaku, who told Yuki that unlike Suguru Geto he does not desire a world without cursed spirits.Refuted byIn the main series, his corpse is controlled by Kenjaku (Japanese: 羂索, Hepburn: Kenjaku), a Curse User with the Cursed Technique: "Brain Transplant," which allows him to take over the bodies of others; Kenjaku uses this on Geto after his death by Gojo at the end of the prequel series.refuted2 against3 points

    • Suddenly, Choso also arrives on the battlefield, surprising Yuji. Geto welcomes him but Choso finally recognizes the curse user as one of his three parents. There is Choso's mother, the cursed spirit who got her pregnant, and the man who tormented Choso's mother to create the Cursed Womb: Death Paintings. Choso hated this person and now they're inhabiting Suguru Geto's body. This person is none other than the evilest sorcerer in history, Noritoshi Kamo!Chapter 134 - Jujutsu Kaisen Wiki primary

It's hard to conclude whether he's the most potent curse user who ever lived, but he's definitely the evilest who would even give Sukuna a run for his money. As for his origins, no one knows where he came from and why.Kenjaku's Origins And Motivations, Explained - CBR analysis
