"Whom Gods Destroy" is a third season episode of the original science fiction television series Star Trek. It is episode #69, production #71, and was broadcast on January 3, 1969. It was written by Lee Erwin, based on a story by Lee Erwin and Jerry Sohl, and directed by Herb Wallerstein. The title is based on a quote often misattributed to Euripides: "Those whom the gods wish to destroy they first make mad." This episode was withdrawn by the BBC in the UK because of 'sadistic plot elements' during the initial run in 1971 and was not shown until a repeat run in January 1994.
