What does the audience know to be true about Opedius?

The audience knows that Oedipus is a tragic hero, destined to fulfill a prophecy that foretells he will kill his father and marry his mother. Despite his intelligence and determination to uncover the truth, he is ultimately blind to his own reality and the consequences of his actions. His tragic flaw is his hubris, which leads to his downfall and the suffering of those around him. This dramatic irony creates a tension between what Oedipus believes about himself and the audience's awareness of his fate.
