What are the main quotes that have the motif of blood and violence? Including those that change the character development in "Macbeth."
There are two quotes, found in Act II, scene ii of William Shakespeare's Macbeth, which denote how the motif of blood and violence are important in the defining of both Macbeth and his wife, Lady Macbeth.
After hearing the prophecy of the witches, Macbeth decides to allow chance to bring him the throne (instead, of him forcing himself upon the throne). After reading a letter form her husband, Lady Macbeth decides to push his rise to the throne. She, believing him far too weak, decides to take things into her own hands and plans the murder of King Duncan.
After the murder, the difference between Macbeth and his wife is made very apparent. Macbeth fears that Duncan's blood will be on his hands forever (seen with his question, "Will all great Neptune's ocean wash this blood / Clean from my hand?"). Lady Macbeth, on the other hand, fails to see the blood as important ("My hands are of your color, but I shame / To wear a heart so white."). She does not see any problem with having feelings of guilt.
As the play progresses, Macbeth feels less and less guilt regarding the murder of Duncan. Instead, he plans the murders of Banquo and Macduff's family. He has certainly changed in his character. No longer does guilt rack Macbeth. Instead, Macbeth's ambition has taken the place of his guilt.
While violence is not stated within the quotes provided, readers can readily denote the violence which lies within murder. At the same time, it could be violent to some the idea that one fails to accept guilt for murder. Murder is a violent act; therefore, the fact that blood is on Macbeth's and Lady Macbeth's hands because of the murder denotes it as a violent symbol.
