Final answer:
Macbeth's mental and emotional state can be characterized as conflicted and deteriorating, marked by guilt, paranoia, and a grim resignation towards the play's conclusion.
Step-by-step explanation:
Macbeth's mental and emotional state at the point of the quotes provided can be described as turbulent and conflicted. From the initial bewilderment and desire for power, Macbeth's psyche delves into guilt, fear, and paranoia as a result of his murderous actions. Notably, after the murder of King Duncan, Macbeth articulates a profound sense of guilt and horror, remarking on the unnaturalness of his deeds, as shown when he says, 'His silver skin laced with his golden blood; And his gash'd stabs look'd like a breach in nature For ruin's wasteful entrance'.
In his dialogue with Lady Macbeth, we witness Macbeth's vacillation between ambition and fear - his wife chastises him for his fears and hesitations, yet Macbeth's determination to proceed despite his trepidation is clear, as seen in 'I am settled, and bend up Each corporal agent to this terrible feat'. As the play progresses, his mental state deteriorates, marked by increasing desperation, aggressive defensiveness, and detachment from reality, culminating in his distracted and resigned demeanor after learning of Lady Macbeth's death.
