Shakespeare presents Lady Macbeth as a figure who initially seems to command the tragedy through language, performance, and emotional pressure. In the extract, she treats hesitation as weakness and turns Macbeth's uncertainty into something shameful, showing how power in their relationship is often exercised through speech rather than force.

Her challenge, 'When you durst do it, then you were a man', weaponises ideas of masculinity. The verb 'durst' suggests courage is something Macbeth must prove publicly, and Lady Macbeth manipulates that pressure to push him towards murder. Shakespeare therefore presents her as someone who understands the values of her world and can bend them to her own purpose.

Elsewhere, Lady Macbeth's plea to be 'unsexed' reveals that she sees ambition and violence as qualities denied to women. This makes her both transgressive and tragic: she reaches for power by rejecting the qualities her society expects of her, but that rejection cannot hold. Her authority depends on suppressing pity, conscience, and vulnerability.

By the sleepwalking scene, Shakespeare overturns her earlier control. The woman who once directed Macbeth is now trapped in compulsive repetition, reliving the blood she tried to dismiss. This collapse suggests that Lady Macbeth is not free from guilt at all; she is simply better at silencing it in the early stages of the play.

Overall, Shakespeare presents Lady Macbeth as powerful but not invulnerable. Her influence drives Macbeth towards action, yet the tragedy finally shows that the performance of strength she creates for herself cannot survive the moral consequences of Duncan's murder.
