Power in Macbeth:
macbeth's yearning for power (to be king, usurped the throne, killed duncan, after being king: abused his power, threatens his servant: go prick your face... hang you up at the nearest tree till famine...)(need to relook)
lady macbeth's yearning for power (to be queen, move up the chain of being, insulted and manipulated macbeth to kill duncan, but in the end overcome by guilt)
macduff (powerful yet dont want power -- killed macbeth, can be king himself, but he wanted only justice and for the rightful king to regain his kingship)
