The respect Jocasta is shown here, exemplifies her power and status as Queen. Normally, women would be disregarded, yet due to her royalty, she is regarded highly.
"I will tell you. I respect you, Jocasta, much more than these men here ..." (Sophocles 770-771).
Jocasta's hubris is exemplified through this quote for she displays her belief that she was able to outsmart the gods, something not considered possible for humans. Due this, her arrogance will eventually lead to her downfall as she continues to disregard the gods.
"Apollo brought neither thing to pass. My baby no more murdered his father than Laius suffered- his wildest fear- death at his own son's hands. That's how the seers and all their revelations mapped out the future. Brush them from your mind" (Sophocles 794-798).
By deciding to abandon Oedipus, Jocasta fulfills the prophecy. The certainty she has in fooling the gods combined with this choice, seals her fate and marks the moment her life is condemned to misery and shame.
"...my son- he wasn't three days old and the boy's father fastened his ankles, had a henchman fling him away on a barren, trackless mountain" (Sophocles 790-793).
"No sir, another shepard passed you on to me ... He called himself a servant of...if I remember rightly-Laius. (Jocasta turns sharply)" (Sophocles 1141-1144).
"Once she'd broken in through the gates, dashing past us, frantic, whipped to fury, ripping her hair out with both hands - straight to her rooms she rushed, flinging herself across the bridal-bed, doors slamming behind her - once inside, she wailed for Laius, dead so long, remembering how she bore his child long ago, the life that rose up to destroy him, leaving its mother to mother living creatures with the very son she'd borne" (Sophocles 1369- 1378).
In this moment, Jocasta has the realization that the prophecy may have come true. It is noted in her body language, for the sudden realization causes her "turn sharply." She first tries to stop Oedipus from digging any further and coming to the same revelation. When she cannot stop the approaching discovery of what has happened, she then takes her own life.
Through this description, the audience feels pity towards Jocasta as she laments over her acceptance of her responsibility. Although she is extremely hubristic and tried so hard to outsmart the gods, the audience remembers here that she does this for she does not want the prophecy to become true. Her mistakes are committed in her effort to remain good and prevent this tragedy from ever occurring. Her grief over how truly awful a sin she has committed is resonant with any who have made mistakes they deeply regret. Hence, catharsis occurs here.
