A Scottish nobleman, and the Thane of Fife. His wife is Lady Macduff, and the two have babies and a young son. Macduff offers a contrast to Macbeth: a Scottish lord who, far from being ambitious, puts the welfare of Scotland even ahead of the welfare of his own family. Macduff suspects Macbeth from the beginning, and becomes one of the leaders of the rebellion. After Macbeth has Macduff's family murdered, Macduff's desire for vengeance becomes more personal and powerful.
