Oedipus Fate vs. free will is one of the most prevailing themes in Sophocles' Oedipus the King. From the outset of the play, Sophocles presents the title character's fate as being preordained, and possibly immutable. The gods have determined that Oedipus will kill his father and marry his mother, thereby causing a great tragedy of events over which Oedipus appears impotent and unable to change.
