The language of Lady Macbeth suggests an overwhelming sense of fierce determination for her husband to possess the ruthlessness of her character. However, the evil persona she adopts fails to shadow the insecurities of her conscience, conflicting with her strong will to murder the king. .
The determination and strength Lady Macbeth possesses is expressed through her powerful soliloquy. In her ruthlessness she cries,.
"Glamis thou art, and Cawdor; and shalt be .
What thou art promised." .
The imperative verb "shalt" shows her strong firmness of intention. She tactlessly believes Macbeth will be king and does not consider the consequences of her presupposing actions. This in turn reveals the impulsive, spontaneous side to Lady Macbeth's character. In her determination she is commanding towards her husband, as she tries to change Macbeth's preventative traits to suit his needs, .
"Hie thee hither, .
That I may pour my spirits in thine ear," .
The alliterative hissing sounds of the letter "h" show a degree of urgency in her tone, and are an early indication of the evil persona she is starting to adopt. The latter can be compared to a metaphor for venom, illustrating Lady Macbeth's intentions to fill Macbeth's mind with the deepest raw cruelty that she is persistent in making herself possess, through expression. Her fear of his kind nature shows he has the ambition but not the disposition,.
"Yet I do fear thy nature; .
It is too full o" the milk of human kindness".
The word "milk" symbolizes metaphorically the purity and goodness of Macbeth's nature (it also represents Lady Macbeth's persona, when she begs the spirits to exchange wholesomeness for gall to make the mind bitter). The mention of poison is an acting contrast to this, showing Lady Macbeth's view that her mind is unlike her husband's. Her commands to Macbeth show that she also has to power of persuasion, not just to change him, but also increasingly to alter herself, and be forcefully deceived into thinking that they can rapidly change their personalities to suit their wishes.
