Banquo's Death and Haunting Return
Think Banquo's influence ends when he dies? Think again - his ghost becomes Macbeth's worst nightmare and represents the consequences of evil actions.
Macbeth fears Banquo because the witches prophesied that Banquo's children will be kings. Since Macbeth and Lady Macbeth can't have children, this prophecy makes Macbeth feel inadequate and threatens his plans for a dynasty.
Even whilst dying, Banquo shouts "Fly, good Fleance!" to save his son. This shows that although Banquo dies, he lives on through his children, and the witches' prophecy about his descendants becoming kings remains alive.
Symbolic Meaning: Banquo's ghost represents Macbeth's guilt and deteriorating mental state - you can't escape the consequences of murder!
The ghost's appearance at the banquet creates terrifying imagery. When Macbeth cries "never shake thy gory locks at me," we see how Banquo continues to threaten Macbeth even in death. The ghost sitting in Macbeth's place symbolically shows that Banquo remains the superior, more honourable man.
The phrase "dare look on that which might appall the devil" uses demonic imagery to show both Banquo's grotesque ghostly appearance and Macbeth's complete mental breakdown. This supernatural punishment reinforces that evil actions have lasting, terrifying consequences.
