Essay I wrote at midnight because I was bored and remembered that this question exists.
“The raven himself is hoarse
That croaks the fatal entrance of Duncan
Under my battlements. 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 th’access and passage to remorse,
That no compunctious visitings of nature
Shake my fell purpose, nor keep peace between
Th’ effect and it. Come to my woman’s breasts,
And take my milk for gall, you murd’ring ministers,
Wherever in your sightless substances
You wait on nature’s mischief. Come, thick night,
And pall thee in the dunnest smoke of hell,
That my keen knife see not the wound it makes,
Nor heaven peep through the blanket of the dark,
To cry ‘Hold, hold!’ “
The phrase “unsex me here” in Lady Macbeth’s first soliloquy show that Lady Macbeth wants her gender role to be separated from what her actual gender is. She loves being female but she wants to not be perceived as female because if she is perceived as a male or anything but female she would be able to manipulate Macbeth into killing King Duncan. This links to the quote “take milk for my gall” because the connotations of milk is childbirth and childcare, and you have to be a person in a very good mindset and be a kind-hearted person to be able to take care of a child, which then links to Macbeth because Lady Macbeth believes that Macbeth is too much of a kind soul to do any deed such as murder.
“Fill me from the crown to the toe top full of direst cruelty” shows how Lady Macbeth wants to be able to guilt trip Macbeth into killing King Duncan because the cruelty illustrates and foreshadows death and murderous or intrusive thoughts.
