‘Macbeth’ by William Shakespeare is a tragedy written in the Jacobean era to act as a cautionary tale about going against the king or committing regicide. The theme of guilt is clearly presented in the play as a force that plagues one's conscience. The play serves as a reminder to the Jacobean audience that disrupting the natural order - particularly committing regicide - can have dire consequences, which we see through the downfall of Macbeth and Lady Macbeth. Guilt immediately haunts Macbeth after Duncan’s murder, revealing that although he was capable of committing regicide, his conscience is not immune to the psychological consequences of his ambition. We can see this when Macbeth questions whether “Will all great Neptune’s ocean wash this blood clean from [his] hand?” Macbeth’s metaphor reveals his overwhelming guilt. The hyperbolic image of an entire ocean being unable to cleanse him emphasises how deeply he feels the weight of his crime, suggesting it has tainted him permanently. The colour imagery of “blood” acts as a symbol for guilt throughout the play, foreshadowing the irreversible consequences of his actions. Shakespeare uses this to show that Macbeth is not inherently evil; instead, his guilt reveals a troubled conscience that deteriorates as ambition overtakes morality. Structurally, this soliloquy isolates Macbeth on stage, reflecting his mental isolation. Shakespeare uses this moment to caution against disrupting the natural order; Macbeth’s guilt is his punishment for violating the Divine Right of Kings. Lady Macbeth attempts to suppress guilt and present herself as emotionally detached and pragmatic, but Shakespeare ultimately reveals that internalised guilt is just as destructive, leading to her psychological unravelling. She dismisses guilt with the minimising phrase, “A little water clears us of this deed.” The adjective “little” trivialises the act of committing regicide which was considered a divine sin in the Jacobean era as it was going against The Divine Rights of King which ultimately shows them going against God. The word “clears” implies a false sense of control over guilt and consequence. This is ironic in light of her later breakdown, revealing how her repression only delays guilt rather than erases it. In contrast to Macbeth’s dramatic guilt, hers is internalised and festers. By Act 5, her guilt manifests through obsessive hand-washing in the line “Out, damned spot! Out, I say!” where the imperative “out” and repetition show her desperation. The “spot” symbolises her mental stain of guilt. Shakespeare uses prose here, breaking from the usual iambic pentameter, to reflect her psychological disintegration. Her death represents the ultimate consequence of denying guilt and trying to escape moral responsibility. As the play progresses, guilt transforms into a toxic psychological force that isolates both Macbeth and Lady Macbeth from one another and from themselves, showing how ambition without morality leads to mental destruction. The metaphor, “O, full of scorpions is my mind, dear wife!” compares Macbeth’s thoughts to venomous creatures, reflecting how guilt has infested his mind. The plural “scorpions” suggests his growing paranoia and internal torment, emphasising that guilt is no longer just emotional; it now shapes his entire perception of reality. Macbeth’s hallucinations, from the dagger to Banquo’s ghost, show how guilt destabilises his mind, isolating him from rationality. Similarly, Lady Macbeth’s detachment from Macbeth in later acts shows how guilt drives a wedge between them. Shakespeare uses guilt as a dramatic device to portray how unchecked ambition leads to inner corruption. Through their descent into madness, he warns that ambition without conscience ultimately leads to ruin, not only socially but spiritually.
