Which characters are profound visions of evil in Macbeth?
There are at least three characters in Macbeth that can be described as "profound visions of evil." The most obvious one is Macbeth himself who fulfills the witches prophesy, no matter what the reason, by killing Duncan. The witches, of course, could also be included in our evil character list. If it weren't for their prophesy, would Macbeth have even considered murder? Would he even be capable of "vaulting ambition"? Perhaps not. In my opinion, however, it is Lady Macbeth that best personifies that "profound vision of evil" that you speak of. She admits late in Act I that Macbeth "is too ful o' th' milk of human kindness" to be able to kill Duncan on his own. Further, she calls on the evil spirits of the world to help her convince her husband to carry out this wicked deed! "Come, you spirits that tend on mortal thoughts, unsex me here, and fill me, from the crown to the toe, top-full of direst cruelty! Make thick my blood, stop up th' access and passage to remorse." A profound vision of evil? I think so.
