Read the excerpt from act 3, scene 4 of The Tragedy of Macbeth. Macbeth is talking to Lady Macbeth after their dinner guests have departed.[Macbeth.] For mine own goodAll causes shall give way: I am in bloodStepp’d in so far, that, should I wade no more,Returning were as tedious as go o’er.Strange things I have in head that will to hand,Which must be acted ere they may be scann’d.
