In Macbeth, famous Shakespeare's tragedy, Macbeth kills king Duncan and Banquo to become a king. Macduff suspects that Macbeth is a murderer, which is why he flees to England and raises an army against him.

In Act IV, Scene II, his wife learns that he has left. Lady Macduff claims that he is crazy for running away, and that he will look like a traitor because of that. She says that her husband does not love her and their children. If he did love them, he would not have left them in such a dangerous place. Her opinion is that Macduff is a coward, and that his decision to go to England was not a wise one.
