Explanation:
Oedipus believes that the shepherd who saw the crime would help him clean his reputation. Oedipus is innocent if this individual still believes it was a gang of killers. He'll know he's guilty if he says it was only one man now.
In Oedipus Rex, Oedipus wishes to find the killer of King Laius in order to put a stop to the dreadful plague that is ravaging Thebes. Oedipus realises that by avenging King Laius, he is also defending himself from the killer.
