Macbeth explores what happens when loyalty collides with self-interest. Discuss.

First performed around 1606 for a Jacobean audience still shaken by the Gunpowder Plot, Shakespeare's tragedy Macbeth interrogates the corrosive consequences of prioritising self-interest over absolute loyalty, examining the ruin that follows when allegiance to the Great Chain of Being is severed.¹ While the play acknowledges that the initial temptation to discard loyalty for self-advancement arises from supernatural manipulation, it maintains that the resulting destruction stems from the deliberate choice to abandon allegiance in pursuit of selfish desires.² Shakespeare consequently warns his Jacobean audience against elevating self-interest above ordained duty, illustrating that a kingdom's stability depends upon unwavering loyalty to the natural order, as treason inevitably consumes both the aspirant and the realm.³

Shakespeare initially presents self-interest as a latent vulnerability within human nature, yet reveals that supernatural equivocation and persuasive manipulation actively corrupt genuine loyalty into treasonous ambition.⁴ Commencing amidst a bleak landscape with "thunder and lightning⁵" enveloping Scotland, the tragedy foreshadows the chaos that awaits, with its seismic atmosphere encompassing the ambiguity of the witches "hover[ing] through fog" who pose as a threat to the Great Chain of Being. The imagery of the thunder symbolises the moral obscurity mirrored in Macbeth's soliloquy as he rationalises that the witches' "truths…cannot be ill", illustrating his burgeoning self-interest as he succumbs under his initial capitulation to the destructive temptation to abandon allegiance. Coupled with the cryptic chant "Fair is foul, and foul is fair", Shakespeare challenges the hierarchy of the Jacobean Great Chain of Being, exploring Macbeth's internal conflict under the reign of supernatural forces that distort humans' perception of loyalty. The supernatural prophecies merely awaken Macbeth's inherent appetite for supremacy, leaving Lady Macbeth to dismantle his remaining allegiance by converting his hesitation into a resolute rejection of duty.⁶ Lady Macbeth's instruction to "look like th' innocent flower but be the serpent under't⁷" metaphorically critiques the duality of deceit and irrepressible self-interest as individuals in the pursuit of power disregard their loyalty and engage in regicide. Manipulating his masculinity through the declaration that he should "be so much more the man", she intensifies his conflict between "vaulting ambition" and "black and deep desires", compelling him to abandon loyalty in favour of self-interest. By succumbing to his self-serving yearnings, Macbeth's hallucination of "a dagger of the mind" symbolises his moral uncertainty and the psychological deterioration associated with his hubristic self-advancement as he believes the vision is guiding him to his destiny, which unavoidably leads to his downfall. Through the witches' equivocations and Lady Macbeth's manipulation, Shakespeare reveals that the abandonment of loyalty for self-interest emerges from both external temptation and internal desire.⁸
