Macduff's Justice and Restoration
Macduff becomes Scotland's moral avenger, believing order can only be restored by ending Macbeth's tyranny. His reaction "horror, horror, horror" to Duncan's murder shows genuine grief, not political calculation.
His devastated cry "all my pretty ones?" after learning of his family's murder reveals authentic human emotion. Unlike other male characters, Macduff isn't ashamed to express grief and vulnerability.
The powerful line "I have no words, my voice is my sword" uses the idiom that actions speak louder than words. Macduff will restore justice through deed, not empty promises.
Symbolic Role: Macduff calling Macbeth "tyrant" gives the play's final moral judgment - he represents justice triumphing over corruption and the natural order being restored.
