Alone, Macbeth ponders the deed that he is about to perform. He is aware of the powerful reasons for murdering the king, but is nagged by self-doubt arising from his fear of retribution both in heaven and on earth and by his likely loss of reputation. However, any such fears are dismissed by his wife in the same practical tone that she used in Act I. Her taunting of her husband's weakness, coupled with the efficiency of her own plan, convince Macbeth that he should take on the "horrid deed."
