Malcolm and Macduff have a conversation. Malcolm attempts to reveal Macduff’s true self to whether he is loyal to Macbeth or not. Malcom does this by saying really bad things about himself, pretending in order to see if Macduff reveals bad things about himself. It turns out Macduff is loyal to Scotland and if Macbeth is loyal to Scotland too then He is loyal to Macbeth. At the time Macduff wasn’t aware that his wife, children and servants were killed. Rosse soon appears on stage telling him what happened. This causes Macduff to have a vendetta against Macbeth, he wants revenge for what he did to his family.
“Cut short all intermission; front to front bring thou this fiend of Scotland and myself; within my sword’s length set him; if he ‘scape, heaven forgive him too!” Said by Macduff, this is his tipping point, he now is setting out for revenge against Macbeth.
