In William Shakespeare's renowned play Macbeth, the theme that power corrupts is strongly depicted through several characters, each of whom follow the "power corrupting" path of lusting for power, doing nearly anything to achieve that power, and ultimately meeting his/her end because of that power. Shakespeare illustrates this theme most vividly through the character of Lady Macbeth, an ambitious woman living in medieval Scotland. She craves for power but is ironically driven crazy by it, for the power reflects the wicked schemes that she contrives to attain power. Moreover, her lust for power overwhelms the morality and good judgment of her conscious mind and causes her to believe that no matter how cruel a deed she carries out, as long as its purpose is to achieve power, she will never feel reprehensible. As a result, Lady Macbeth declares that blood can be easily washed away, but she eventually finds that the guilt that the blood symbolizes refuses to abandon her and becomes too much for her to bear, causing her ultimate deterioration.
To begin, Lady Macbeth's insistence that blood can be effortlessly distilled provokes the beginning of her downfall. Early on, Lady Macbeth acts as the mind and the will in plotting an assassination attempt, thirsting for the power that she could achieve if the attempt was successful. Furthermore, she manipulates her tentative husband, Macbeth, to murder the Scottish king, Duncan, by redundantly questioning his manhood, which he undoubtedly feels that he has to prove. By assassinating the king, Lady Macbeth would improve her position to become the authoritative Queen of Scotland. On the other hand, after killing Duncan, Macbeth is paralyzed with horror from what he has done. He is only barely clinging on to sanity when Lady Macbeth continues to influence him, declaring, "A little water clears us of this deed. How easy is it, then!" (2.2.86-87). Again, she is challenging Macbeth's manhood by implying that if he is truly a man, then he should easily be able to handle the guilt.
