Lady Macbeth could not kill duncan because what?
Answers
Lady Macbeth is not a courageous person; she is a bully who finds courage only in the belittlement and degradation of others. Oh, she plans well and speaks bravely, but she lacks the drive to commit the acts she desire to happen. As noted in another’s response, Lady Macbeth remarks that she couldn’t kill Duncan herself because he resembled her father as he slept. This implies that she attempted to do the crime herself, but the loving memory of her father prevented her action. That, I would say, is simply an excuse to satisfy herself.
She portrays herself as a heartless, cunning, power-hungry character who feels no guilt or remorse, will do anything to achieve her goals, and will not tolerate a husband who is anything less than she is. While she appears to be cold and callous, it is all a charade, the facade of a bully. We see glimpses into her true character repeatedly through much of the rest of the play, but she largely hides her fears and self-doubt behind anger and vicious verbal attacks on her dear husband.
