Love is blind

Macbeth sees Lady Macbeth as his business partner and nothing more. Macbeth has no affection for her because they have no real relationship other than the name of marriage. He brushes off the continual throws of emasculation but her dominating ambition puts him under her spell. The audience sees Lady Macbeth as pure evil. She is nothing but an ambitious and heartless soul that cannot even be considered human. She has no humanity and in a way she wants to lose it considering that she wishes to not feel guilty about the murder of the king.
