Lady Macduff, innocence lost

Lady Macduff is the personification of a mother in Elizabethan times. She guarded her son fiercely while the guards came to kill them. Lady Macduff is a true parent protecting her son and loving him. This is far unlike Lady Macbeth's speech about dashing out the brains of her babe. Lady Macduff speaks kindly to her child she is protective and loving. This was not like anyone else. The Witches, Hecate or Lady Macbeth were vile, nasty without conscience. Lady Macduff was angry with her husband for abandoning their family. 

LADY MACDUFF	Wisdom! to leave his wife, to leave his babes,
	His mansion and his titles in a place
	From whence himself does fly? 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. (6-14) Act 4, Scene 2

 She questions her husbands decision to leave and tend to business over his family. A woman should not question her husband but Lady Macduff does and rightly so!  She and her son share the sweetest conversation in the play. They discuss how they will manage to get through this difficult time. Her son conveys how easy it would be to kill an honest man because there are so many liars and swearers in the world. It is one of the saddest and most poignant parts of the movie watching this conversation take place. It humanizes her character in comparison to the other players.
