Macbeth presents ambition as a destructive force that, once unleashed, consumes the individual entirely — transforming a loyal warrior into a tyrannical murderer, and ultimately proving that the pursuit of power without moral restraint leads only to isolation, madness, and death.
Point 1
Lady Macbeth is the initial catalyst for Macbeth's ambitious action, using manipulation and gender-shaming to override his conscience and propel him toward regicide.
“Look like th'innocent flower, but be the serpent under't” [Lady Macbeth] Act 1, Scene 5
- The biblical allusion to the serpent in Eden casts Lady Macbeth in a diabolical role — she consciously adopts the methods of evil for the sake of ambition.
- The imperative mood ('Look... be') reveals Lady Macbeth's dominance as the strategist of Duncan's murder, inverting expected Jacobean gender dynamics.
- The juxtaposition of 'innocent flower' and 'serpent' encapsulates how ambition requires concealment — the Macbeths must disguise their true intentions behind hospitality.
“Unsex me here, and fill me from the crown to the toe top-full of direst cruelty” [Lady Macbeth] Act 1, Scene 5
- Lady Macbeth's invocation to the spirits reveals that ambition requires the suppression of natural human qualities — compassion, femininity, and conscience must be discarded.
- The phrase 'top-full' suggests she wants to be entirely consumed by cruelty, leaving no room for doubt or mercy.
- Shakespeare suggests that unchecked ambition is fundamentally unnatural — it requires a person to become something other than human.
Point 2
Macbeth recognises the moral horror of his ambition even as he pursues it, revealing a man whose conscience battles his desire for power throughout the play.
“I have no spur to prick the sides of my intent, but only vaulting ambition, which o'erleaps itself” [Macbeth] Act 1, Scene 7
- The equestrian metaphor of 'vaulting ambition' presents ambition as a rider who jumps too high and falls — foreshadowing Macbeth's inevitable downfall.
- Macbeth acknowledges that he has no legitimate reason ('spur') to kill Duncan — only raw ambition drives him, exposing the hollowness of his justification.
- The phrase 'o'erleaps itself' is proleptic: ambition that exceeds natural limits will destroy itself, which is exactly Macbeth's trajectory.
“Stars, hide your fires; let not light see my black and deep desires” [Macbeth] Act 1, Scene 4
- The imperative addressed to the stars reveals Macbeth's awareness that his ambition is morally 'black' — he already knows his desires are wrong.
- The personification of light as a moral witness suggests Macbeth fears divine judgement, connecting ambition to the violation of the Great Chain of Being.
- Shakespeare uses the imagery of darkness to establish that ambition operates in secrecy and shame — it cannot survive exposure to moral scrutiny.
Point 3
After the murder of Duncan, Macbeth's ambition becomes a self-perpetuating cycle of violence — each crime demands another to maintain his grip on power.
“I am in blood stepped in so far that, should I wade no more, returning were as tedious as go o'er” [Macbeth] Act 3, Scene 4
- The extended metaphor of wading through a river of blood presents murder as a journey with no return — Macbeth is trapped by his own actions.
- The word 'tedious' is chilling: murder has become not horrifying but merely inconvenient, revealing the atrophy of Macbeth's moral sense.
- Shakespeare shows that ambition creates a momentum of its own — once the first moral boundary is crossed, each subsequent crime becomes easier.
“To be thus is nothing, but to be safely thus” [Macbeth] Act 3, Scene 1
- Having achieved the crown, Macbeth discovers that ambition provides no satisfaction — power brings only paranoia and the need to commit further violence.
- The word 'nothing' is devastating: the thing he murdered for has turned out to be worthless, exposing the fundamental emptiness at the heart of his ambition.
- This drives the decision to murder Banquo, proving that ambition's appetite is never satisfied — each achievement demands more.
Point 4
Macbeth's final soliloquy reveals the ultimate consequence of unchecked ambition: a nihilistic despair in which life itself has been drained of all meaning and purpose.
“Tomorrow, and tomorrow, and tomorrow, creeps in this petty pace from day to day” [Macbeth] Act 5, Scene 5
- The epizeuxis (triple repetition) of 'tomorrow' creates a slow, relentless rhythm that mirrors the monotony of Macbeth's joyless existence after ambition has consumed everything.
- The verb 'creeps' personifies time as insidious and meaningless — the urgency that once drove Macbeth has collapsed into nihilistic emptiness.
- Shakespeare shows that ambition's final destination is not power but despair — Macbeth has gained a kingdom and lost his humanity.
“Life's but a walking shadow, a poor player that struts and frets his hour upon the stage” [Macbeth] Act 5, Scene 5
- The extended theatrical metaphor reduces all human ambition to empty performance — 'struts' captures arrogance, 'frets' captures anxiety.
- The culmination — 'a tale told by an idiot, full of sound and fury, signifying nothing' — is Shakespeare's most nihilistic statement, spoken by the man who sacrificed everything for power.
- The dramatic irony is devastating: Macbeth's ambition has proved the very meaninglessness he now perceives — his pursuit of power was itself 'signifying nothing'.
