Macbeth's Downward Spiral
The Story of Macbeth
Lady Macbeth's Desire for Power
Nothing Good Happens At Night
This quote is talking about how the night has been had strange events, hearing screams of death, the owl howling at night, and fierce winds. Not only does this quote represent symbolism, it also represents foreshadowing. The night being "unruly" foreshadows that bad events are to come, and it also represents bad things have happened.
Scaredy Cat
Lady Macbeth compares Macbeth to a cat who won't catch a fish because he's scared of taking chances and getting his feet wet. This expresses an analogy because, just like the cat, Macbeth is acting cowardly, and afraid to take a chances by killing Duncan.
A Change in Heart
"Let light not see my black and deep desires. The eye wink at the hand; yet let that be, which the eye fears, when it is done, to see" (1.4.59-61).
The first quote represents Macbeth at the beginning of the book, loyal to the King, and fighting for his kingdom. As time progresses on, the second quote, explaining Macbeth's murderous thoughts, shows he hopes for Duncan to be murdered, though he doesn't wish to see it. These quotes show Macbeth is a dynamic character, since at the beginning of the play he was loyal and loved the King, but later then wishes Duncan to be killed for his own selfish wants, so he kills Duncan to get what he wants.
