As Noritoshi Kamo, he kills and tortured numerous beings, including impregnating a woman and aborting the children 9 times to craft the Death Painting curses. In the modern age, in the body of Suguru Geto, Kenjaku organizes the deaths of numerous humans under the Disaster Curses and manipulates the Shibuya Incident for massive death, [[YouHaveOutlivedYourUsefulness only to eliminate his final ally Mahito]]. Announcing the Culling Game to get new sorcerers to fight to the death and whittle one another down, Kenjaku starts worldwide conflicts, kills numerous sorcerers, and finally plans to merge the entirety of humanity into one tortured being [[ForTheEvulz just so he might see what will happen]].
** [[Characters/JujutsuKaisenMahito Mahito]], the youngest disaster [[Characters/JujutsuKaisenCursedSpiritsAndCurseUsers Curse]], represents the fear and hatred humans have towards each other, and seeks [[KillAllHumans the eradication of mankind]]. A [[PsychopathicManchild sadistic killer]], Mahito uses his power [[{{Biomanipulation}} Idle Transfiguration]] to toy with the lives of humans, including children, by transforming them into monsters and weapons, all while they are aware of their suffering and beg for help. Meeting a troubled young man named Junpei, Mahito [[TheCorrupter toys with his head to turn Junpei into a killer for his own amusement]], murdering Junpei's mother to frame a bully, and eventually turning Junpei into a monster who dies in sheer anguish, all while laughing at Yuji's failed attempt to save him. Later on, Mahito takes part in the Shibuya incident to seal [[Characters/JujutsuKaisenSatoruGojo Satoru Gojo]] by transforming over a thousand people into monsters and slaughtering hundreds of other civilians, all while attempting to break Yuji's mind and soul for petty revenge and enjoyment by killing his mentor Nanami in front of him and one of his best friends, Nobara. A cruel and sadistic Curse lacking the care for his fellow Curses that his comrades share, Mahito lives up to being the worst humanity has to offer, even for a Curse.

* ''Anime/Kite1998'': [[DirtyCop Akai]] raises orphaned girls [[CorruptionOfAMinor to become]] his own personal [[{{Tykebomb}} assassins]], preaching justice to them while really using them to wipe out criminals both to stroke his own ego or remove underworld competition for his own actions. Killing Sawa's parents, Akai uses her as little more than a weapon and [[SexSlave sex toy]], raping her as he pleases, gifts her earrings filled with her own parents blood, and notably [[WouldHurtAChild repeats the molestation on his other girls]]. His crimes dwarfing even those of his fellow rapist partner-in-crime, Akai is utterly disgusting.

** [[SugaryMalice Nui Harime]] is the [[FauxAffablyEvil seemingly]]-[FaceOfAnAngelMindOfADemon sweet]] Grand Couturier of REVOCS and Ragyo Kiryuin's most powerful agent. A [[GigglingVillain giggling]] psychopath who is eager to see the culmination of Life Fibers [[KillAllHumans annihilating all human life on Earth]], Nui kicked off Ryuko's quest for revenge when Nui viciously murdered the girl's father, Isshin Matoi. Continuing to bulk up REVOCS' power and the creation of COVERS with her own two hands, Nui later causes all sorts of mischief by turning Ryuko into a rampaging monster before playing a key role in her horrible MindRape and brainwashing. After a failed attempt to force Ryuko and her allies to massacre each other, Nui merges her essence with the Original Life Fiber and [[FusionDance combines with Ragyo]] as a last-ditch effort to ensure the annihilation of humanity.
