Step-by-step explanation:
The motivation of Lady Macbeth in Shakespeare's tragedy is a complex mixture of personal ambition and love for her husband, Macbeth. You asked what motivates Lady Macbeth.
While she does exhibit a deep affection for Macbeth, her actions are primarily driven by a love of power. This is evident in the play, where Lady Macbeth pushes Macbeth towards the regicidal act that would place them at the throne. Her love for Macbeth is intrinsically linked with her own desire for power and status, which is clear when she challenges his masculinity and urges him to pursue the crown.
