Macbeth and the Witches’ Prophecy: Does Fate Require Action?

In Macbeth, the witches’ predictions make a future of royal power seem possible, but they do not tell Macbeth to murder Duncan. The crucial question is why he refuses to wait and see whether events will carry him to the throne. At first, Macbeth entertains the thought that chance might make him king without his intervention. He abandons that patience because the prediction awakens a desire for certainty: he wants the crown, fears losing the opportunity, and believes action can secure what fate has merely suggested. Shakespeare therefore presents prophecy chiefly as an invitation Macbeth chooses to act upon, not as a force that determines his crimes. The witches open a possibility; Macbeth’s decisions make that possibility a violent plan.

Macbeth’s early thought of letting chance take its course is important because it establishes that he sees an alternative to murder. Yet passivity cannot satisfy him for long. The prophecy gives him a possible destination, not a timetable or a promise that the path will be easy. He begins to treat uncertainty itself as a danger: if he waits, he may have to endure suspense or risk that the crown will not become his. That impatience helps explain why he moves from imagining kingship to considering Duncan’s death. The choice is not simply between fate and free will; it is between accepting uncertainty and trying to control the future. Macbeth chooses control.

When Macbeth considers Duncan’s assassination, his reasoning exposes what waiting would require: accepting the present rather than forcing the predicted future. He understands the consequences of violence, including the possibility that violence will return upon its maker. He recognizes that Duncan trusts him as kinsman, subject, and host, and that Duncan has ruled well. Macbeth even admits he has no motive to proceed except “vaulting ambition.” The prophecy has stirred his imagination, but his own reasoning identifies ambition—not an order from the witches—as the force pushing him toward murder. He proceeds because the possibility of kingship matters more to him than the obligations he understands.

Macbeth’s decision is not inevitable even after Lady Macbeth urges him on. He tells her that they will proceed no further, noting that Duncan has honored him and that he has earned the goodwill of others. This reversal shows the real meaning of his earlier hesitation: Macbeth can step back, at least temporarily, when he considers what the murder would cost. But the crown remains more compelling than the security of doing nothing. The witches do not remove his capacity to refuse; rather, their prediction gives his ambition an imagined reward. His choice to return to the plot shows why the option of waiting loses its appeal: waiting protects his moral obligations, but it cannot guarantee the power he wants. (Source passage P2)

Once Macbeth becomes king, he discovers that reaching the predicted position does not end his fear. Banquo observes that Macbeth has gained the titles the witches promised and suspects that Macbeth acquired them foully. Macbeth, in turn, fears Banquo and remembers the prediction that Banquo’s descendants will rule. He resists leaving that future to unfold and arranges Banquo’s murder, also targeting Fleance. This decision extends the same impatience that first led him to reject waiting: rather than accept an uncertain future, Macbeth tries to eliminate the people who seem to threaten his control. Prophecy supplies a possibility to fear; Macbeth makes that fear a reason for violence. (Source passage P3; Source passage P4; Source passage P5)

The vision of future kings intensifies Macbeth’s anxiety but still does not dictate a response. He sees Banquo’s line continuing and reacts with alarm. The vision may confirm that the witches’ predictions have reach beyond Macbeth’s own reign, but it cannot make him commit any particular crime. His decision to attack Banquo has already revealed how he answers unwelcome possibilities: he tries to prevent them from mattering. The scene therefore complicates a simple claim that Macbeth invents everything the witches foretell. Their supernatural knowledge may be real within the play, yet Macbeth remains responsible for choosing to fight the future rather than endure uncertainty. (Source passage P8)

Macbeth’s attack on Macduff’s household shows how completely his desire to act first has overtaken judgment. When he learns that Macduff has fled, Macbeth resolves that his first thoughts will become his first actions. He then plans to seize Macduff’s castle and kill the members of his household. No prophecy in this moment requires such a response. Macbeth chooses immediate violence because he cannot tolerate the possibility that Macduff may oppose him. The decision is more than a single crime: it is the final expression of his habit of treating uncertainty as a threat to be destroyed. By now, he no longer waits for fate or weighs alternatives; he tries to make every fear disappear through force. (Source passage P9)

A serious counterargument is that the witches do shape events: their riddles influence Macbeth, and Hecate describes illusions designed to draw him toward confusion and false confidence. The play does not present human choice as untouched by supernatural forces. But influence is not compulsion. Macbeth repeatedly chooses the most violent response to what he hears, and the prophecies do not make his actions morally necessary. When Birnam Wood appears to move, he recognizes that the witches’ equivocation has misled him. Even then, he chooses to arm himself and face the approaching army. Shakespeare allows fate and deception to matter while preserving the distinction between what Macbeth is told and what he decides to do. (Source passage P7; Source passage P10)

Ultimately, Macbeth rejects waiting because the prophecy makes power imaginable while leaving its arrival uncertain. He wants to replace that uncertainty with control, and ambition persuades him that violence can secure the future. His deliberation about Duncan demonstrates that he understands the alternatives and the moral cost; his later decisions show the consequences of repeatedly refusing patience. The witches may reveal or distort what lies ahead, but they do not turn prediction into command. Shakespeare’s tragedy depends on Macbeth’s choice to act as though every uncertain future must be forced into the shape he desires. Fate invites him; ambition makes him answer.

How the argument works

The essay answers why Macbeth does not wait by connecting impatience and the desire for control to his ambition. It then tests the interpretation against his deliberation over Duncan, his fear of Banquo’s descendants, and his attack on Macduff’s household. Each episode distinguishes what the prophecy suggests from what Macbeth chooses. The counterargument acknowledges the witches’ supernatural influence, while showing why influence alone does not make Macbeth’s crimes inevitable.
