"Would you agree with Malcolm that Lady Macbeth is a "fiend-

As soon as this is heard, the first reaction is to believe that Macbeth is associated with the witches and their mischievousness. However. It is revealing in Scene Two where King Duncan says.
             "What he hath lost, Macbeth hath won." .
             That we learn about how Macbeth is so courageous and fearless at war that he has earned his title as Thane of Cawdor, which completely changes the picture in our minds of Macbeth. Now Macbeth seems to be some sort of heroic figure, and all ideas of him being somewhat evil himself are destroyed. It is his wife who has the wicked quality in the relationship. .
             In Scene three, the witches reveal to Macbeth and Banquo their predictions for Macbeth's fortune:.
             "All hail Macbeth! hail to thee, thane of Galmis!.
             All hail Macbeth! hail to thee, thane of Cawdor!.
             All hail Macbeth! that shalt be king hereafter.".
             Macbeth really begins to consider what he has just been told and really starts to believe in the witches" prophecies. In fact, so much so that he feels the need to write a letter to his wife to inform her of what had happened. It seems to me that as Banquo pointed out, Macbeth would like for what the witches had predicted to come true but he does not have the nerve to accomplish the task of becoming king through being deceitful and dishonest, and is secretly relying on his wife to obtain the leadership role and help him decide what he should do. .
             Also, another clue which might show that Macbeth is looking for support from Lady Macbeth is that he says "They have more in them than mortal knowledge" (talking about the witches), which suggests that he may be a little intimidated by the powers of the witches, and doesn't really no how to interpret what they are saying. .
             Fortunately for Macbeth, his wife is at once extremely enthusiastic and comes up with a sly and cunning plan for how they can achieve their evil goal. This is one of the first impressions we receive of Lady Macbeth, and we can tell almost immediately that she is associated with evil and slyness from the way she is so instantly keen on making Macbeth become king, even if she had to achieve this through wicked and fiendish means.
