Macbeth's state of mind isn't good at all. First off, he's completely numb from all of the terrible things that have happened, he doesn't feel
anything anymore. When he is threatened and when his wife dies - he barely responds. He is completely cold:
<span>
"I have almost forgot the taste of fears:
The time has been, my senses would have cool'd
To hear a night-shriek, and my fell of hair
Would at a dismal treatise rouse and stir
As life were in't: I have supp'd full with horrors..."
