She attempts to excuse herself, explaining "had he not resembled my father as he slept, I had done it", which exposes her inner cowardice and ingrained fear of patricide. Lady Macbeth is manipulative as she operates within a Liminal gender, she takes advantage of alleged feminine weakness, when it works in her favour, yet brutally rejects it if it represses her. Shakespeare may have been creating a subtle commentary on how arbitrary (illogical) gender roles were, as this is a typical theme within his works.
