Sex and Darkness in Shakespeare's Macbeth Shakespeare's Macbeth presents more than the simple tale of a murder and revenge. Macbeth wants to be king, and Duncan stands in his way. However, Macbeth hesitates. His wife, Lady Macbeth, must urge him on strongly, like a rider whipping a horse.

When the blood begins to flow, it becomes a metaphor for sex. Lady Macbeth displaces her desire to destroy her husband onto Duncan, and Macbeth displaces his desire to dominate his wife sexually onto Duncan. The poor victim of these psychological mechanisms, Duncan, is killed more like the victim of a rape than the victim of a murder. When his blood flows, and his life ebbs away, Lady Macbeth feels a sexual orgasm, and Macbeth feels the loss of his erection at the end of the act.
