ese few references to honor, the symbol of blood now changes to show a theme of treachery and treason.Before Duncan's murder, Macbeth imagines seeing a dagger floating in the air before him. He describes it, "And on thy blade and dudgeon gouts of blood, Which was not so before. There's no such thing: It is the bloody business which informs Thus to mine eyes." (II, i, 57-60)The blood imagery in this passage obviously refers to treason, ambition, and murder. This imagery shows the beginning of Macbeth's character transformation from a person of nobility, honesty, and bravery to that of treachery, deceit, and evil. After Macbeth kills Duncan, the meaning of blood begins to change. In Act II Scene ii Macbeth’s hands are covered in blood. Later on, Lady Macbeth’s are too. Macbeth reacts to the blood very differently then Lady Macbeth. Macbeth sees the blood as the symbol of his action and as the symbol of his guilt; Macbeth cannot believe what he has done and is in shock. "Will all great Neptune's ocean wash this blood Clean from my hand? No; this hand will rather The multitudinous seas incarnadine, Making the green one red." (II, ii, 71-75) He imagines that all of the water from the ocean could not clean his hands of the burden of guilt that weighed so heavily on his tormented mind. He pictures Duncan’s blood staining the entire ocean red. This passage illustrates that the act of murder has changed Macbeth's character. No longer does the blood suggest an image of ambition; it now symbolizes guilt and remorse. The passage also shows how no amount of water could clean Macbeth’s guilty conscience. Again, blood is referred to when Malcolm and Donalbain are discussing what to do. Malcolm says: "there's daggers in men's smiles: the nearer in blood,/ the nearer bloody." (II,iii, 139-140), meaning that their closest relatives are likely to kill them. Again, blood is being used to describe treason, murder, and death....
