How can Oedipus be clear of guilt in

Oedipus cannot be clear of guilt because he willingly killed a man and slept with his mother.

However, it can be argued that Oedipus was not morally responsible for his actions. He did not know that he was killing his father or sleeping with his mother. When he learned the truth, he was horrified and blinded himself out of shame. Oedipus was a tragic figure who was punished for crimes that he did not know he was committing.
