The Fall of Man
The ancient Greek notion of tragedy concerned the fall of a great man, such as a king, from a position of superiority to a position of humility on account of his ambitious pride, or hubris. To the Greeks, such arrogance in human behavior was punishable by terrible vengeance. The tragic hero was to be pitied in his fallen plight but not necessarily forgiven: Greek tragedy frequently has a bleak outcome. Christian drama, on the other hand, always offers a ray of hope; hence, Macbeth ends with the coronation of Malcolm, a new leader who exhibits all the correct virtues for a king.
Macbeth exhibits elements that reflect the greatest Christian tragedy of all: the Fall of Man. In the Genesis story, it is the weakness of Adam, persuaded by his wife (who has in turn been seduced by the devil) which leads him to the proud assumption that he can "play God." But both stories offer room for hope: Christ will come to save mankind precisely because mankind has made the wrong choice through his own free will. In Christian terms, although Macbeth has acted tyrannically, criminally, and sinfully, he is not entirely beyond redemption in heaven.
Fortune, Fate, and Free Will
Fortune is another word for chance. The ancient view of human affairs frequently referred to the "Wheel of Fortune," according to which human life was something of a lottery. One could rise to the top of the wheel and enjoy the benefits of superiority, but only for a while. With an unpredictable swing up or down, one could equally easily crash to the base of the wheel.
Fate, on the other hand, is fixed. In a fatalistic universe, the length and outcome of one's life (destiny) is predetermined by external forces. In Macbeth, the Witches represent this influence. The play makes an important distinction: Fate may dictate what will be, but how that destiny comes about is a matter of chance (and, in a Christian world such as Macbeth's) of man's own choice or free will.
Although Macbeth is told he will become king, he is not told how to achieve the position of king: that much is up to him. We cannot blame him for becoming king (it is his Destiny), but we can blame him for the way in which he chooses to get there (by his own free will).
Kingship and Natural Order
Macbeth is set in a society in which the notion of honor to one's word and loyalty to one's superiors is absolute. At the top of this hierarchy is the king, God's representative on Earth. Other relationships also depend on loyalty: comradeship in warfare, hospitality of host towards guest, and the loyalty between husband and wife. In this play, all these basic societal relationships are perverted or broken. Lady Macbeth's domination over her husband, Macbeth's treacherous act of regicide, and his destruction of comradely and family bonds, all go against the natural order of things.
The medieval and renaissance view of the world saw a relationship between order on earth, the so-called microcosm, and order on the larger scale of the universe, or macrocosm. Thus, when Lennox and the Old Man talk of the terrifying alteration in the natural order of the universe — tempests, earthquakes, darkness at noon, and so on — these are all reflections of the breakage of the natural order that Macbeth has brought about in his own microcosmic world.
Disruption of Nature
Violent disruptions in nature — tempests, earthquakes, darkness at noon, and so on — parallel the unnatural and disruptive death of the monarch Duncan.

Many critics see the parallel between Duncan's death and disorder in nature as an affirmation of the divine right theory of kingship. As we witness in the play, Macbeth's murder of Duncan and his continued tyranny extends the disorder of the entire country.
Lady Macbeth is the focus of much of the exploration of gender roles in the play. As Lady Macbeth propels her husband toward committing Duncan's murder, she indicates that she must take on masculine characteristics. Her most famous speech — located in Act I, Scene 5 — addresses this issue.
Clearly, gender is out of its traditional order. This disruption of gender roles is also presented through Lady Macbeth's usurpation of the dominate role in the Macbeth's marriage; on many occasions, she rules her husband and dictates his actions.
Reason Versus Passion
During their debates over which course of action to take, Macbeth and Lady Macbeth use different persuasive strategies. Their differences can easily be seen as part of a thematic study of gender roles. However, in truth, the difference in ways Macbeth and Lady Macbeth rationalize their actions is essential to understanding the subtle nuances of the play as a whole.
Macbeth is very rational, contemplating the consequences and implications of his actions. He recognizes the political, ethical, and religious reason why he should not commit regicide. In addition to jeopardizing his afterlife, Macbeth notes that regicide is a violation of Duncan's "double trust" that stems from Macbeth's bonds as a kinsman and as a subject.
On the other hand, Lady Macbeth has a more passionate way of examining the pros and cons of killing Duncan. She is motivated by her feelings and uses emotional arguments to persuade her husband to commit the evil act.
