From reading Oedipus Rex and the tragedy that resulted from that story, we then looked at the story of Antigone, Oedipus' daughter. In this story, the two son's of Oedipus duel to be ruler and end up killing each other. One son gets a proper burial from Kreon but the other is left out to the birds. Antigone, thinking this is wrong, takes her sister and they both bury the brother even though they are risking getting themselves killed as well.
A lot of the tragedy centered around Kreon since he was stubborn in his opinions. He even says, "Will the nation tell me what orders I can give?" Even though Kreon is very much connected with Antigone, he refuses for her to bury her brother. Because he is stubborn like this, Antigone goes and buries the brother anyway and Kreon sends her to her death.
Towards the end of the story, Kreon realizes the huge mistake he has made. Antigone and Haimon both committed suicide. Antigone hanging herself in the same way Jocasta, her mother, did in Oedipus Rex. "Kreon has shown there is no greater evil than men's failure to consult and consider." If he were able to change his ways before, then no one would have died. Sometimes it takes a tragedy for someone to learn a lesson. In this instance it took the death of Oedipus' children to show Kreon to change his stubborn ways.
