In Macbeth, how does Macduff describe the turmoil in Scotland?

In Act 4 Scene 3 of Macbeth, Macduff
describes the turmoil in Scotland.  He tells Malcolm that Scotland is under the control of a
tyrant and that many senseless deaths have occurred.  He says that the nation is miserable and
hopeless because Macbeth is not the rightful king of the land.  The men do not feel safe under
Macbeth's rule.  Macduff cries for his country.  When Rosse arrives and reports that Macduff's
family has been murdered, the men immediately suspect that Macbeth is responsible, and Macduff
blames himself for being absent.  The men vow to take back Scotland and return peace to the
land.
