Does someone by any chance know the a real kill ritual/spell, preferably in satanism?
I don’t know what you mean by ‘the a real kill ritual/spell”. If you want to learn about ritual and its psychological roll in Satanism, go read “The Satanic Bible” or “The Satanic Rituals” by Anton Szandor LaVey. The former includes a “conjuration of destruction”, to deal with anger against an enemy. Both books are available wherever paperbacks are sold. If you’re planning on killing somebody, don’t. That’s illegal.
