How does the chorus help Creon in the play Antigone?

In Antigone, the chorus tries to help Creon see the error of his ways. For example, at the end of Scene 2, the Choragos (the leader of the chorus) questions Creon's motive for wanting to also put Ismene to death even though she is not guilty of breaking the decree. The Choragos uses rhetorical questions to get Creon to see that his actions might be made in stubborn haste. Further, at the end of Scene 5, after Tiresias has departed, the Choragos tells Creon that he must at once free Antigone and give Polynices's body a proper burial. The Choragos says that Creon must not delay and that he must perform these acts with his own hand and not by proxy. By doing this himself, Creon takes direct responsibility for his own actions and makes amends for the wrong decisions that he has made. So, the chorus acts as a moral compass against which Creon can see the error in his unwise decisions.
