"You, plotting to kill me, kill the king—I see it all, the marauding thief himself scheming to steal my crown and power!....Your treachery—you think I'd never detect it creeping against me in the dark?"
Oedipus is so prideful in his wealth and power that he doesn't even trust those closest to him (Creon) and thinks they're plotting to take what he has.
"You are fated to couple with your mother, you will bring a breed of children into the light no man can bear to see—you will kill your father, the one who gave you life!' I heard all that and ran. I abandoned Corinth, from that day on I gauged its landfall only by the stars, running, always running toward some place where I would never see the shame of all those oracles come true."
His prideful nature makes Oedipus believe he can escape his fate told by the oracles.
