Loss in Macbeth

How does Shakespeare present the theme off loss in ‘Macbeth’?
In the play ‘Macbeth’ Shakespeare incorporates the theme of loss in many different ways. Shakespeare includes several different types of loss, each presenting multiple challenges to individual characters; these are inflicted by emotional and personal losses. This theme of loss also helped the reader a better understanding on the play at the very beginning the inevitable downfall and tragedy is foreshadowed. The theme helped create a tragic setting for the play for the main protagonist, Macbeth, who during the play we had seen rise then inevitably hit rock bottom.
    Throughout the play the protagonist, Macbeth, gradually loses many things, some of which were very important, defining the personality of the character, but as the play continues we see him continuously fall off the rails, and his identity spirals out of control. This downfall begins as soon as he decides to kill King Duncan. We can see this when Macbeth states “I’m convinced, and I commit every part of my body to this terrible event.” This is at the point of the play where Macbeth’s downfall begins and he gradually changes into someone other than who he used to be. He bows down to the ruthless greed inside him and he allows it to consume him, which undoubtedly crushes whatever loyalty and friendship between Macbeth and King Duncan, which finally leads to the death of the King.
  After Macbeth kills King Duncan, there are clear signs of guilt, we know this as Macbeth quotes “Will all great Neptune’s ocean wash this blood clean from my hand.” This indicates the feelings present for King Duncan, but not even that could rally against Macbeth’s vaulting ambition. This proves vital to his downfall as the emotion shown is tremendous in comparison to when others are killed, which never seemed to bother Macbeth. This could show to us that Macbeth was always on the verge to his ruthlessness, but the killing of King Duncan was the final push...
