What Have We Done?

I don't know what's wrong with me.  I used to want all of this.  The power.  The control.  But now it's getting to me.  Men are dead because of my husband and I.  How could we do this?  I feel so guilty, I don't know how to get rid of this feeling.  I've been sleep walking through the castle, talking of things such as how my hands will never be cleaned of the blood.  Macbeth is fine with everything, he's even up for killing more people.  I don't know how he does it.  How can he not see that this is affecting so many people.  I can't do it anymore.  I can't live like this... goodbye...
