The id, ego, and superego exist to be powerful forces that represent the thoughts and actions of people. Freud's details these ideas and they are exemplified through the characters in Antigone. The id is helpful in evaluating Antigone's rebellious actions. The ego helps in analyzing Creon's monarchial character. The superego is helpful in describing Ismene's conforming nature. The actions of the characters in Antigone are key in identifying how all three concepts play into human thought and behavior.
