We see the triumph of evil in a man with many good qualities. We are made
aware that the potential for evil is frighteningly present in all of us and needs only the wrong circumstances and a relaxation
of our desire for good. The good in Macbeth cries out poignantly through his feverish imagination, but his worldly ambition,
the influence of Lady Macbeth, and the instigation of a supernatural power all combine to crush his better nature.By the end
of the play Macbeth has collapsed beneath the weight of his evil, and the desperate tyrant has so isolated himself from society—and
from his own moral sensibility—that for him life seems "a tale / Told by an idiot, full of sound and fury, / Signifying
nothing' (Act 5: Scene 5: Lines26-28). His once good nature is now bad. This is the basic theme and plot of the
play, " foul is fair, and fair is foul."
