Why does Jocasta reject the possibility that Oedipus is the murderer of Laius?

Jocasta's rejection of the idea that Oedipus is the murderer of Laius aligns with her belief that a group of highwaymen killed Laius. This reflects her desire to hold onto a version of events that absolves Oedipus of any potential guilt in the situation. Throughout the play, Jocasta's understanding of fate and prophecy is complicated; she initially dismisses the oracles and believes that Laius's death was the result of a random act of violence rather than a fulfilled prophecy regarding her son. By attributing Laius's murder to external forces, she attempts to distance Oedipus from the horrific implications of the prophecy. This choice highlights her denial as she struggles with the horrific implications of the truth and seeks to protect both her husband and herself from the dread associated with fate.
