sadique

from the name of the Marquis de Sade, known for his libertine writings depicting the pleasure of harming others. The term 'sadism' was coined or recorded in the posthumous 1834 edition of Boiste's Universal Dictionary of the French Language; it was reused with 'sadistic' in 1862 by Sainte-Beuve in his commentary on Flaubert's Salammbo; it was independently taken up in 1886 by the psychiatrist Krafft-Ebing in his Psychopathia Sexualis, which popularized it; it was directly used by Freud in 1905 in Three Essays on the Theory of Sexuality, which definitively established it.
