One possible interpretation of the play is as follows: “Oedipus is punished not for any fault in himself, but for his ignorance. Not knowing his family history, unable to recognize his parents on sight, he is blameless; and in killing his father and marrying his mother, he behaves as any sensible person might behave in the same circumstances.” Do you agree with this interpretation?

I think there's a strong case to be made that Oedipus is not without blame. When he visits the oracle at Delphi, the mouthpiece of the god Apollo, and hears the prophecy that he will kill his father and marry his mother, he decides that he would not go home to Corinth. Oedipus thinks that he can avoid the prophecy, proudly believing that his will can overcome that of fate or that of a god. In thinking that he can outwit Apollo, he moves to Thebes, surmising that he can never fulfill the prophecy if he is not near the individuals he believes to be his parents, and yet this is precisely the action that leads him to kill his father (on the road to Thebes) and marry his mother (once he gets there and is named king). He does not understand that the gods know more than he does, or that he—a mere mortal—is fallible. Had he not been ruled by pride, who knows what might have happened? As it is, Oedipus's pride compels him to think himself more powerful than fate, and he pays a heavy price.
