LOVE IS BLIND

The audience is able to see Lady Macbeth much more objectively than Macbeth does.  We are able to see her ambition and power hungry desire as a vice instead of a trait of quality like Macbeth does.  She emerges as the "wears the pants" type in attitude as well as in action. Macbeth takes what she says and encourages as automatic truth while the audience can take it all with a grain of salt.
