Macbeth and Lady Macbeth best characterize this idea. Both plan and participate in the violent, bloody murder of King Duncan, playing upon his love and trust to slay him as he sleeps peacefully within their castle. When the deed is done, both wear Duncan's blood on their hands. After claiming Duncan's crown as King of Scotland, Macbeth continues to choose violence as the means to maintain his power. He coldly orders the murders of Banquo and Fleance (Fleance escapes, but Banquo is slain.), and in absolute cold blood, he orders the slaughter of Macduff's wife and children, as well as all his servants.
