Witchcraft In Macbeth

Lady Macbeth shows a spiked interest in “metaphysical aid” which she does use later on in the play when she “calls the spirits”, she talks about witchcraft playing a big part in the future crowning of Macbeth, and displaying dramatic irony as we know she later uses witchcraft. Dark magic was a very unusual and taboo thing to use in plays in the Shakespearean era, this can create the reader to feel suspense.
In other parts of the play, ambition is presented in other ways; when Macbeth plots against Banquo. Macbeth creates lies and tells the murderers that it's Banquo's fault that their lives are ruined, "That it was he...our innocent self". This shows a much darker side to Macbeth's ambition, and shows he will kill his own best friend in fear
of his interference, Macbeth is also shown to echo his wife and challenge the murderer's masculinity as did Lady Macbeth, this is used to demean and dehumanise them into doing his dirty work. Macbeth's echoing could also show his ambition is not as strong as it may seem, since he is using Lady Macbeth's words. He makes out that Banquo is the man in the wrong by making him out to be crazy, this creates irony since Macbeth is only using this to make himself look sane, since he doesn't have the same mental stability as Banquo does. The text suggests Macbeth's ambition is not his own, since it is firstly suggested by the witches and Lady Macbeth even though Macbeth hints at it in Act 1.
