The psychology of ambition: The great reversal of roles in Macbeth
In Brief
- Lady Macbeth's ambition is fueled by a concentrated, absolute force of will, leading her to consciously suppress her natural humanity and remorse (her famous 'unsexed' plea).
- Macbeth's ambition is plagued by his potent imagination, which functions as a conscience by projecting premonitory images of the crime and its horrific consequences, leading to hesitation.
- The murder triggers a profound psychological reversal: Macbeth becomes hardened and increasingly tyrannical, seeking oblivion in action, while Lady Macbeth succumbs to the 'compunctious visitings' she had tried to eliminate.
- The tragedy demonstrates that deliberately choosing evil severs ambition from human nature, resulting in the annihilation of the self and proving that unnatural deeds breed unnatural troubles.
The tragedy of Macbeth is an examination of ambition, structured not as a simple cautionary tale but as a profound psychological drama built upon a “systematic principle of contrast” [1]. At its heart is the dynamic between Macbeth and Lady Macbeth, two figures ignited by the same passion for power but who embody it in fundamentally different ways [2]. Their shared ambition drives them toward a single criminal act, yet their internal journeys toward and away from that moment reveal a stark divergence. The play presents a constant struggle between opposing natures, making their intertwined downfall a complex study of human psychology in the face of temptation and consequence .
Shakespeare uses this marital dynamic to explore the multifaceted nature of ambition itself. Macbeth’s ambition is filtered through a potent and active imagination, a faculty that serves as the seat of his conscience and breeds profound hesitation [3, 4]. His better nature expresses itself not through clear moral prohibitions but through horrifying, premonitory images . In sharp contrast, Lady Macbeth’s ambition is characterized by an immediate, concentrated force of will that seems, at first, far more powerful and decisive [5, 6]. Her resolute purpose and “masculine firmness” become the indispensable catalyst for their shared destruction, making her the initial, and ultimate, deciding influence on the action [7].
The Hesitant Imagination vs. The Resolute Will
At the outset, Macbeth is depicted not as a villain-in-grain but as a man possessing a noble nature wrestling with a dark temptation [8, 9]. His character is defined by a deep-seated conflict between his ambition and his inherent “milk of human kindness” [10, 11]. This internal struggle is externalized through his powerful imagination, which presents the potential crime and its consequences with such vivid horror that it almost prevents him from acting [12, 13]. The spectral dagger is not merely a supernatural omen but a projection of his own agitated mind, a mind in which his better nature has incorporated itself into alarming images that are deeper than his conscious thoughts . His energy, therefore, springs not from conviction but from anxiety and agitation .
Lady Macbeth provides the perfect foil to her husband's faltering virtue . Where his imagination breeds inaction, her will is absolute and immediate. She perceives his imaginative conscience as a weakness and seizes control, framing the regicide not as a treacherous crime but as a heroic enterprise, “this night’s great business” [14, 15]. Her formidable strength lies not in superior intellect but in an immense courage and an obdurate force of will, allowing her to maintain self-control while acting a part . While Macbeth recoils from the future, she sees the path to greatness and never flinches from the objective until it is achieved .
Her famous invocation to be unsexed is a clear acknowledgment that she is doing violence to her own fundamental nature [16, 17]. She does not act out of a lack of humanity but from a conscious, willed decision to suppress it. She prays to have the “access and passage to remorse” stopped up and fears the “compunctious visitings of nature,” a direct plea for hardening that Macbeth himself never makes . This highlights the essential difference in their internal conflicts: Lady Macbeth knows she must become a monster to achieve her aims, whereas Macbeth fears that the monstrous act will reveal the man he already is. Her will is a weapon turned inward against her own womanhood, a concept Victor Hugo identified as central to her entire character [18].
The Catalyst and the Crime
In the play's first half, Lady Macbeth is undeniably the commanding figure, serving as the “ultimate deciding influence” on the tragic course of events . She masterfully manipulates her husband’s anxieties, challenging his manhood and courage to overcome his moral reservations [19, 20]. Her ambition is presented as deeply intertwined with his, and even primarily for his sake, making her not merely a co-conspirator but the engine of their shared ascent [21, 22]. She takes the superior position, directs the affair, and animates him with a vision of glory that she herself has embraced so completely that she can see it in no other light .
While they share an ambition, its texture and goals differ. Lady Macbeth’s ambition appears more superficial, satisfied with the external trappings of power and the name of queen, without concern for the legitimacy of her subjects' loyalty [23]. Macbeth’s ambition, however, is for something more intangible that the crown itself cannot provide, a fact that leads to his profound and painful disillusionment once the deed is done [24, 25]. This disparity helps explain both the intensity of her resolve before the crime and the depth of his torment after it. For her, the act is the goal; for him, it is merely a gateway to a new form of suffering.
The murder itself is the pivot upon which their roles reverse. For Lady Macbeth, the successful execution of the plot represents a peak of “strained exaltation” which vanishes almost immediately, never to return . For Macbeth, the act of murder unleashes the very forces his imagination had foreseen. His mind becomes “full of scorpions,” and the anxiety that once caused hesitation now drives him relentlessly toward further action as a means of seeking oblivion from his thoughts [26, 27].
The Great Reversal of Roles
In the aftermath of the murder, a profound psychological transformation takes hold, leading to a complete inversion of their original characters. Macbeth, who once staggered under the weight of his purpose, becomes hardened and callous as he plunges deeper into guilt [28]. He becomes proactive in his tyranny, anticipating threats and banishing remorse for past crimes by meditating on future mischief . His imagination, once a conduit for his conscience, now becomes a source of paranoid fear that spurs him to relentless and cruel action, cementing his path toward ruin . He sustains himself only by the intoxicating momentum of bloodshed .
Conversely, Lady Macbeth, whose strength of will appeared invincible, succumbs to the very human weaknesses she scorned . While her husband finds a desperate purpose in continued action, she is left without that stimulus and is instead “troubled with thick-coming fancies” . The conscience she so violently suppressed returns to haunt her, not when she is awake and in command of her will, but when she is asleep and defenseless [29]. The woman who mocked “air-drawn daggers” is ultimately destroyed by an internal, unshakable vision of blood, a retribution that demonstrates her initial inhumanity was a performance, not a reality [30].
This dramatic reversal underscores one of the play's central ironies: in this tragic world, a person's thought, when translated into action, is often transformed into its opposite [31]. Lady Macbeth, who attempted to dash out her humanity, is destroyed by its resurgence when she is hounded to death by the smell of a stranger’s blood [32]. Meanwhile Macbeth, who agonized over the moral implications of his actions, devolves into a tyrant who clings to an earthly existence he finds miserable, fighting to defend a crown that has brought him only despair [33].
The tragedy of Macbeth, therefore, is not simply about the perils of ambition, but about its complex psychological structure, which Shakespeare explores through the contrasting faculties of will and imagination [34]. The couple’s downfall reveals that these two aspects of the human mind can both fuel and shatter a person’s aspirations. Lady Macbeth’s concentrated will proves potent enough to initiate the tragedy but is ultimately too brittle to withstand the psychological consequences of the crime . In contrast, Macbeth's powerful imagination, which at first serves as a moral brake, becomes the very engine of his escalating tyranny once the initial boundary has been crossed .
Ultimately, the play demonstrates the profound moral disaster that befalls those who deliberately choose evil, severing their ambition from their own nature [35, 36]. Macbeth finds that his crown has brought him all the horrors of the life to come, while Lady Macbeth is destroyed by the very “compunctious visitings” she sought to eliminate . Their shared destruction is a powerful illustration that “unnatural deeds do breed unnatural troubles,” revealing that the true tragedy lies not in failing to achieve a goal, but in the irredeemable corruption of the self in its pursuit [37].
