Violent metaphor: In employing a violent metaphor, Macduff contends that the restoration of Scotland's natural order necessitates physical violence - his ambition is to rightfully restore Scotland. Thus, the initial upheaval, brought about by Macbeth's violent tyrannical means, mandates a similar force to rectify the natural order that has been disrupted.
Macduff is the archetype (perfect- example) of the avenging hero, motivated by revenge. Despite his personal motivations rooted in revenge, the nobility of his intentions shines through. His ambitious pursuit of dismantling Macbeth single-handedly to restore order is materialising into a reality.
Short sentence: The short sentence reflects the short amount of time that Scotland will have to continue to suffer - by slewing Macbeth Scotland can be rightly governed and flourish under divine ordain.
"bleed, bleed, poor country" (Act 4)
Personification: Macduff laments (grieves) Scotland, personifying the nation to underscore his profound emotional bond but also reflects the pervasive (quickly spreading) sense of loss and despair that permeates Scotland.
Macduff's sorrow, then, becomes emblematic (symbolic) of the collective grief felt by the nation, further highlighting the immense political upheaval and chaos that has befallen Scotland due to Macbeth'styranny and violence (cruel/oppressive leadership).
Repetition: The recurrent motif (symbol/theme throughout) of "bleed" highlights Macduff's despair about Scotland's progressive demise, effectively encapsulating Macbeth's misanthropic (disliking of others) disposition.
Macduff's patriotism (love for his country) emphasises Macbeth's ruthless indifference to dismantling Scotland but also serves as a compelling juxtaposition to the inherent nobility expected of a rightful king.
