The play offers moral lessons, notably that "power corrupts." Macbeth transforms from a loyal soldier to a murderer driven by ambition. Initially noble, his desire for power leads to moral decay after killing King Duncan. Guilt is another theme; Lady Macbeth, initially ruthless, is tormented by her actions, leading to madness and suicide. Although Shakespeare doesn't explicitly state a moral, the play explores themes like the corrupting influence of power and the inescapability of guilt.

In "Macbeth," Macbeth and Lady Macbeth are punished through overwhelming guilt, leading to their mental unraveling and deaths. Macbeth's paranoia and tyrannical actions culminate in his beheading by Macduff. Lady Macbeth, consumed by guilt, descends into madness and commits suicide. Malcolm is rewarded for his bravery and loyalty by becoming King of Scotland, restoring order, and granting earldoms to his loyal supporters. Macduff, though not explicitly rewarded, plays a crucial role in ending Macbeth's tyranny.

The essential moral issue in Macbeth is the conflict between ambition and morality. Macbeth faces the dilemma of seizing power by fulfilling the witches' prophecy through murder, sacrificing his conscience for personal gain. Initially reluctant, Macbeth's "vaulting ambition" leads him to murder King Duncan, spurred by Lady Macbeth's encouragement. This decision results in guilt and paranoia, illustrating how abandoning moral integrity for ambition can lead to self-destruction and irreversible consequences.

Shakespeare distinguishes good kings from tyrants in Macbeth by contrasting the illegitimate and corrupt Macbeth with the virtuous and legitimate Malcolm. Macbeth seizes the throne through murder, leading to his descent into tyranny and bloodlust. In contrast, Malcolm embodies moral virtue and dynamic leadership, ultimately restoring rightful kingship to Scotland. Shakespeare uses Malcolm's testing of Macduff in Act 4, Scene 3, to highlight the qualities of tyranny versus legitimate rulership.

The night King Duncan is murdered, unnatural events occur, including a violent storm, strange screams, and darkness during daytime. Birds of ill omen, such as owls and ravens, are mentioned, symbolizing death and chaos. These events disrupt the natural order, reflecting the Elizabethan belief in the divine right of kings, where such disruptions are seen as consequences of regicide. Shakespeare uses these elements to foreshadow the disorder Macbeth's rule will bring to Scotland.

The main conflicts in Macbeth include Macbeth's internal struggle with ambition and guilt, his conflict with Lady Macbeth, and the external conflict with other characters like Banquo and Macduff. These conflicts are closely tied to themes such as the corrupting power of unchecked ambition, the moral consequences of one's actions, and the destructive nature of power and guilt.

In Shakespeare's Macbeth, the theme of good versus evil is central, depicted through the internal and external struggles of characters. Macbeth, initially portrayed as valiant and honorable, becomes consumed by ambition and the influence of the witches and Lady Macbeth, leading to his moral downfall. Despite the dominance of evil throughout the play, symbolized by the witches and Macbeth's tyrannical reign, good ultimately prevails with Malcolm's rightful ascension to the throne. Shakespeare suggests that while evil is potent, it does not triumph over good.

Shakespeare conveys several moral messages in Macbeth, including the corrupting power of unchecked ambition, the consequences of moral transgressions, and the inevitable downfall that follows betrayal and murder. The play illustrates how ambition can lead to one's destruction when it is not tempered by ethical considerations, and how guilt and paranoia can consume those who commit heinous acts.

In Macbeth, the theme of evil is explored through the protagonist's descent into moral corruption. Macbeth's ambition and subsequent actions, spurred by the witches' prophecies and Lady Macbeth's manipulation, lead him to commit regicide and numerous atrocities. The play illustrates how unchecked ambition and the influence of malevolent forces can transform a noble individual into a tyrant consumed by guilt and paranoia.

In Macbeth, Shakespeare uses the imagery of darkness, light, and blood to symbolize themes of evil, guilt, and moral conflict. Darkness often represents evil and concealment, as seen when characters like Macbeth and Lady Macbeth invoke it to hide their malicious intents. Light symbolizes goodness and truth, which are overshadowed by darkness as the play progresses. Blood imagery underscores guilt and the consequences of violent actions. This chiaroscuro technique highlights the struggle between good and evil throughout the tragedy.
