To show the theme of corrupting power when it is unchecked, Shakespeare applies the motifs of blood in Macbeth to further the effect of this greed. The blood symbolizes the guilt of both Macbeth and Lady Macbeth, as it stains their conscience like blood on a white carpet. This motif appears from the begging, with the opening battle between the Scots and the Norwegian invaders. Macbeth’s hallucinations of a bloody dagger portray the bloody course in which Macbeth is about to launch. The final outcome is the “stains of blood” which haunt Macbeth after Duncan’s death and disturb Lady Macbeth’s slumber.
