What would be a good thesis for an essay about who is responsible for Duncan's death in Macbeth?
My teacher assigned us an essay about: Who is resposible for King Duncan's death in Macbeth? Macbeth or Lady Macbeth?
Any answer to this question would have to begin by looking at Act I, Scenes 5 and 7. In Act I, Scene 5, Lady Macbeth recieves a letter from her husband describing his meeting with the witches. She resolves then to do what is necessary to push her husband toward his destiny, no matter what it takes. Fearing that her husband is too full of the "milk of human kindness," she asks the "spirits/That tend on mortal thoughts" to:
...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 to remorse...
In Act I, Scene 7, when Macbeth is vacillating about committing the murder, she steels him by questioning his manhood, proclaiming that she would dash out the brains of her own infant rather than break a vow, which is what Macbeth would be doing if he did not follow through with what he said he would do in his letter to her. Macbeth decides to go through with the murder, and his wife even plans it for him. It is still a matter of debate whether Lady Macbeth should bear the ultimatel responsibility for the murder, but any interpretations of her culpability should take these two scenes into account.
thanks that helped a lot!
