Lady Macbeth Takes Control
The moment Lady Macbeth reads about the prophecies, she becomes the driving force behind Macbeth's path to kingship. Her declaration "Shalt be what thou art promised" shows there's no hesitation - she's already decided Duncan must die.
Shakespeare presents their marriage as surprisingly equal for the time period. Macbeth calls her his "dearest partner of greatness", showing genuine affection and trust. However, Lady Macbeth quickly takes charge, fearing her husband is "too full o'th' milk of human kindness" to seize the crown.
Her famous "unsex me here" speech reveals her belief that feminine qualities like compassion are weaknesses. She literally asks evil spirits to remove her womanhood so she can commit murder without guilt. The repeated use of "my" shows her determination to control every aspect of the plan.
Key Point: Lady Macbeth's character completely defied expectations for both Shakespeare's audience and the medieval setting - women were meant to be submissive, not ambitious masterminds.
The imagery of darkness runs throughout the scene, from the "hoarse raven" (a symbol of death) to her plea for "thick night" to hide their deeds. This shows she knows murder is wrong but wants to escape divine judgment.
When Macbeth arrives, Lady Macbeth immediately coaches him with imperative verbs, worried he'll give away their intentions. Her advice to "look like th' innocent flower but be the serpent under't" establishes the play's central theme of appearance versus reality.
