I believe Macbeth is an equivocator and an example of this is in Act 1 Scene 7 when Macbeth says ‘ This even-handed justice commends th’ ingredience of our poinon’d chalice to our own lips’. Here Macbeth is admitting and showing that he is aware that killing Duncan is a very bad deed by referring it as a ‘poinon’d chalice’ in the form of a metaphor. Not only that but Macbeth says that this shouldn’t even happen to Duncan but rather him instead. Macbeth is showing guilt and regret on agreeing to kill Duncan.
