In "Macbeth," Shakespeare explores the theme of kingship through various characters and events, contrasting the noble qualities of a good king with the tyranny of a usurper.
King Duncan is portrayed as the ideal king, honoured and loved, whose murder by Macbeth is seen as a crime against nature, symbolised by unnatural events like a falcon being killed by an owl and Duncan's horses turning wild.
Macbeth, on the other hand, becomes a tyrant, feared and resented. His reign is marked by fear, lies, and a reign of terror, highlighting the stark difference between a rightful king and a tyrant. This contrast is further exemplified in Macbeth's own recognition of Banquo's "royalty of nature," feeling inferior to Banquo's natural leadership qualities. Shakespeare's portrayal of kingship in "Macbeth" serves as a commentary on the nature of power, leadership, and the consequences of usurping the throne through treachery
