Notorious occultist Aleister Crowley supposedly cursed a doctor who later mysteriously died of a sudden infection

A closer look

Aleister Crowley absolutely loved branding himself as the wickedest man in the world, which mostly involved ruining dinner parties and issuing petty magical curses. When a prominent occult critic named Ralph Shirley crossed Crowley, the angry magician supposedly performed a dark ritual specifically targeting him. The doctor mysteriously died of a sudden blood infection shortly after. Whether it was actually dark magic or just the terrifying lack of antibiotics in the 1920s remains a hotly debated topic among hardcore occult nerds.
