LOVE IS BLIND

In Macbeth, Lady Macbeth seems ruthless in her plan to make her husband king.  She is willing to do everything and anything to make it happen, appearing to be a little crazy.  So we, as an audience, see Lady Macbeth as being heartless and desperate.  Contrarily, Macbeth sees the bravery and strength in her that he does not see in himself.  He just sees her as being selfless and only trying to help him take the throne.
