Raiga Kurosuki
Another best twisted anime character of all time is Raiga Kurosuki. A jonin from Kirigakure and a member of the Seven Ninja Swordsmen of the Mist, Raiga Kurosuki was known as the Thunder of the Hidden Mist. He was likewise an Anbu prior to his desertion from the community. Raiga and his sidekick Ranmaru joined the Kurosuki Family as criminal bosses after leaving their village.
Naruto has a vast cast of characters, but the plot still features a number of insane shinobi. But the most underappreciated figure, Raiga Korusuki, has established himself as the most twisted person. Danzo Shimura was a psychopath, but at least he knew what he wanted. Hidan, on the other hand, was merely a crazed lunatic with a pea brain.
Raiga Kurosuki was a terribly troubled, harsh, and lonely person throughout his time in Kirigakure. He killed everyone during his missions without any regard for morality or a specific reason, and he would start to cry anytime he did so. Raiga asked every day what the meaning of existence was. Because of his strange belief, which states that people would have a greater perspective on life when they die, Raiga loves to bury people alive. He even used to cry at their funerals, which just goes to show how twisted and sadistic he was.
