A Faustian bargain is a deal in which a person sacrifices moral integrity, values, or even their soul in exchange for power, knowledge, success, or another form of personal gain. The term comes from the German legend of Faust, who sold his soul to the devil for unlimited knowledge and pleasure. In theatre and literature, this concept often explores themes of temptation, ambition, and the consequences of greed. An example is Seymour in Little Shop of Horrors, who agrees to feed Audrey II in exchange for fame and love.
