peripetia, overzealous (obsessive), tumultuous fortune, flustering, manifestations of his guilt, extrapolated evil, fragmented mind, conscience plagued with guilt
Macbeth becomes overzealous in his indulgence in murder.
Duncan was a moment of peripeteia (a sudden reversal of fate/things go wrong) for Macbeth, yet this is not confirmed until the murder of Banquo ensues.
Duncan's death causes a series of unexpected events to play out largely beyond Macbeth'scontrol.
His fate has been taken out of his hands and though he relentlessly attempts to regain power over his fortune, he fails.
Upon learning that Fleance escaped murder, Macbeth acknowledges his tumultuousfortune, "in time will venombreed/no teeth for th'present".
Yet his hubris (pride) blinds him into a false sense of security, suggesting that danger is not yet imminent.
Banquo's ghost serves as a symbol to expose Macbeth's failure to manipulate fate as despite believing that Banquo is "safe" (murdered successfully), he immediately comes to haunt him.
Macbeth is denied any semblance (hint) of safety.
The banquet scene is Macbeth's opportunity to gain respect as King, both Macbeth and Lady Macbeth are overzealous in their welcoming of guests.
"Welcome" is repeated by both Macbeth and Lady Macbeth which gives the impression of flustering, their guilt is threatening their composure.
Structurally, it is important to note that the murderer enters before Macbeth can sit down with his guests.
Ironically, his past actions interrupt his ability to assimilate with his peers and noblemen as king.
This reinforces that his kingship is unnatural and disrupts the divine right of kings.
The bloody apparition of Banquo is a physicalmanifestation of Macbeth's guilt, it makes it tangible but also serves to expose him to his guests and break his composure.
It is the beginning of his downfall as his guilt obtains power over him.
It appears the power dynamic between the Macbeths begins shifting in Act 3.
Macbeth begins echoing the former sentiments of Lady Macbeth suggesting he has extrapolated her evil.
Macbeth claims they must "make our facesvizards to ourhearts" which is reminiscent of "look like th'innocent flower but be the serpent under't".
This characterises Macbeth as a marionette of evil influence - he echoes both the witches in their lexis (word choice) in Act 1 and his wife.
Macbeth - "Make our facesvizards to our hearts"
This extends the idea of appearances vs. reality as "vizards" suggests they should wear masks to conceal their true nature.
Although Macbeth is growing to be bloodthirsty and tyrannical it appears he is fragile and malleable as a character, he fails to demonstrate any qualities of a respectable king to epitomize the truth that he is disrupting the naturalorder.
Macbeth tells his wife, "I am inblood"
Previously, the bloodmotif (reoccurring symbol for the consequences of murder) was merely his hands, yet now it has enrobed his entire body, and by extension his entire sense of being.
Macbeth tells his wife, "I am in blood" and "Should I wade no more, returning were as tedious"
He admits he cannot return to a position of virtue or innocence so it is easier for him to continue on a murderous path.
Macbeth's response to fear and guilt has transitioned from being horrified to indulging further in heinous acts, murder now becomes means of self-preservation.
Lady Macbeth discourages Macbeth from murdering Banquo, "You must leave this", yet he is trapped within the momentum of evil and dismisses her.
"Be innocent of the knowledge, dearestchuck"
"innocent" could be seen as a mockery of Lady Macbeth saying "look like the innocent flower" because her reality is more alike to that, conforming to feminineexpectations.
It is ironic how Macbeth now overpowers Lady Macbeth through feminineepithets which belittle her, much as she previously done to him.
