I suppose there is a bit of Faust in all of us. Consider being given eternal knowledge and omnipotence. Would you only use it to better yourself? Faust is an example of the inherent flaw in man. Faust makes a bargain with the Devil and squanders it on sophomoric pranks and worldly desires. God never really gives up on him but I think that is a separate issue. Faust a morality tale exactly about the immorality of man. I suppose he does come to a sort of self-realization at the end but the effect remains that it is too little too late.
