YOU'RE ALWAYS A WOMAN TO ME

Macbeth sees his wife as a person who is looking out for his best interests, and to be more exact their best interests as a couple.  He sees her as a person who is trying to encourage him to do things that will better himself, and that will help him grow as a person.  In actuality, though, Lady Macbeth is just a power hungry, back stabbing hag who wants to rule Scotland, and she does not really care about people, only her wants.
