Blood as a dominating theme in "Macbeth" by Shakespeare

I am going to prove that in the play Macbeth, a symbol of

blood is portrayed often(and with different meanings), and that

symbol. Perhaps the best way to show how the symbol of blood

play progresses, he becomes a treacherous person who has become

identified with death and bloodshed and shows his guilt in

injured in a valiant battle for his country. In the next

passage, in which the sergeant says 'Which smok'd with bloody

execution', he is referring to Macbeth's braveness in which his

sword is covered in the hot blood of the enemy.

make herself insensitive and remorseless for the deeds which she

is about to commit. Lady Macbeth knows that the evidence of

blood is a treacherous symbol, and knows it will deflect the

guilt from her and Macbeth to the servants when she says 'smear

the sleepy grooms with blood.', and 'If...
