Question

In Macbeth, Act II, Scene iii, after killing Duncan, he says "To know my deed, 'twere best not know myself." My English teacher interpreted these lines as saying that Macbeth doesn't want to think of the consequences, but does anybody have any other interpretations?

Answer 1

Well, your teacher is right. Macbeth, after having committed the crime, is now feeling guilty of what he has done. He is feeling ashamed of his deed, and more of himself. That's why, he wishes that he would not have known himself, so that he could get over the guilt
