"That death and nature do contend about them, Whether they live, or die." (Act 2: 2) Lady Macbeth has drugged the guards and cannot tell if they are dead of alive, nor does she care.The owl that shrieked marked the death of Duncan, the sound like bells before an execution. The image conveys that Macbeth and Lady Macbeth are equally as guilty with the murder. Lady Macbeth did not commit the murder, but she convinced Macbeth to do it therefore she shares just as much of the blame as Macbeth.
This image shows Lady Macbeth being very two faced. It looks like she's all innocent but when you look in the mirror you see her true reflection and what her deep desires. And it could represent how she was so determined to get to the top that she was willing to make her husband kill the king, and maybe that's where their relationship became compromised and doomed.
