Sadist

It is the name given to the act of deriving sexual pleasure from inflicting pain or suffering on another person. The term originates from the French philosopher and sadistic storyteller, Marquis de Sade. The opposite of sadism, from the perspective of the person experiencing the pain, is... masochism Masochism is the feeling of deriving sexual pleasure from being inflicted with pain or suffering. It usually involves sexual fantasies of being beaten, humiliated, tied up, tortured, etc. Sometimes one person becomes a slave and the other puts a leash on them. The name comes from Leopold von Sacher-Masoch, a 19th-century writer known for his novel "Venus in Furs," which has predominantly masochistic content.
Although sadomasochism emerged in the 19th century, it has become popular today.
Sadism, derived from the Marquis de Sade, and masochism, named after Sacher-Masoch, are both considered to develop from the same pathological process and are often used interchangeably to describe a behavioral disorder, therefore they are preferably referred to together.
