Tragedy of Macbeth
Lady Macbeth is the one to blame
"From this time such I account thy love. Art thou afeard to be the same in thine own act and valor as thou art in desire? Wouldst thou have that which thou esteem'st the ornament of life, and live a coward in thine own esteem, letting 'I dare not' wait upon 'I would', like the poor cat i' the adage" (1.7.43-50). Lady Macbeth's determination to become queen takes over her and she uses the tactic of reverse psychology to make her husband feel like less of a man, and a coward for not letting what he secretly wants to do take over his kindness and loyalty toward the king. She compares him to a poor cat who won't catch a fish because it fears wet feet.
"Yet do I fear thy nature. It is too full o' the milk of human kindness the catch the nearest way....That I may pour my spirits in thine ear and chastise with the valor of my tongue and all the impedes thee from the golden round which fate and metaphysical aid doth seem to have crowned withal" (1.5.16-31). Lady Macbeth is unsure that Macbeth will be able to follow through with the acts in the prophesies. He is loyal to his king and loves him very dearly. She fears Macbeth is too kind to go against Duncan. Even if it means she has to go against her own husband to get what she wants, she will do it.
"Come, you spirits that tend on mortal thoughts, unsex me here, and fill me, from the crown to the toe, top full of direst cruelty! Make thick my blood; stop up the access and passage remorse....That my keen knife see not the wound it makes nor heaven peep through the blanket of darkness to cry 'Hold, hold!'" (1.5.46-60). Lady Macbeth fears that Macbeth will not do what needs to be done, so she calls upon spirits to make her not a lady anymore. So that she can take matters into her own hands and kill Duncan herself only with the slightest hope that heaven will not see what she does.
"Marry, sir, nose-painting, sleep, and urine. Lechery, sir, it provokes, and unprovokes; it provokes the desire, but it takes away the performance. Therefor much drink may be said to be an equivocator with lechery: its makes him and is mars him, and disheartens him; makes him stand to, and not stand to; in conclusion, equivocates him in a sleep, and, giving him the lie, and leaves him" (2.3.27-35). The porter is hungover from the night before when Lady, and Macbeth got him drunk. Shakespeare uses comic relief to cushion the fact that Duncan was just murdered.
"Out, damned spot! out I say! One; two. Why then 'tis time to do't. Hell is murky. Fie, my lord, fie! a soldier and afeard? What need we fear he knows it, when no one can call our pow'r to accompt. Yet who would have thought the old man would have so much blood in him....What will these hands ne'er be clean?" (5.1.34-42). The blood on Lady Macbeth's hands symbolizes the guilt that she has for helping kill Duncan. It also symbolizes that she is going even more insane, considering she's talking about the blood and her guilt in her sleep.
"By the pricking of my thumbs, something evil this way comes" (4.1.45). The weird sisters are referring to Macbeth as the evil one. Which isn't a good sign because Macbeth has always been seen as kind and loyal to his king, and for 3 witches that can reasonably be held responsible for the death of Macbeth and others, to call him evil signifies that Macbeth is turning into something he is not and something bad is bound to happen from it.
He is so kind and reasonable.
His wife, the lady, the other,
Is a cruel and terrible wife for him
For him to listen was solely her fault.
She wanted him to fall, and break, and tear.
And her actions become guilt she can't bare.
She turned him, evil beyond all meaning.
From a man once, gentle, kind, and gleaming.
Her craze drove both of them beyond insane.
Macbeth, a killer, and now a dead man,
Whose corpse may rest in peace and forgiveness.
A tampered mind shall never be punished.
Evil wife, may you die with misery.
