Read the excerpt from act 4, scene 2 of The Tragedy of Macbeth. Lady Macduff is lamenting the fact that her husband has fled from Scotland to England and left her and their children behind.

Lady Macduff. He loves us not;
He wants the natural touch: for the poor wren,
The most diminutive of birds, will fight,
Her young ones in her nest, against the owl.
All is the fear and nothing is the love;
As little is the wisdom, where the flight
So runs against all reason.

What does Lady Macduff imply about Macduff through the hyperbole "All is the fear and nothing is the love”?

He is concerned solely for his own safety.
He lacks generosity toward his wife and children.
He is too timid to be a good father to his family.
He leaves his family because he is afraid of them.
