Copied from the Oedipus Rex group - and one which I think puts it in a nutshell for you.
Oedipus possesses pride and a desire for power. His relentless pursuit of information is what brings about his own downfall. Had he been able to let go of his need to "know all", he would have remained ignornant to the destructive news, as so many encouraged him to do. Pride would not allow their opinions to be heard.
