MACBETH 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; Direness, familiar to my slaughterous thoughts Cannot once start me. Re-enter SEYTON Wherefore was that cry?
Macbeth,William Shakespeare, 5.5. 9-15
Macbeth reminisces about how he use to be frightened of hearing screams of what he would later find would be that of his dying wife. With his hands stained with blood, he lacks the emotions to have fear making him a true tyrant. The same situation occurs in Edward II after Edward stains his hands with the blood of the nobles and doesn't completely fear his own death in the end.
