Revenge is an act of passion; vengeance of justice. Injuries are revenged; crimes are avenged.
Why seeketh thou revenge, O man! with what purpose is it that thou pursuest it? Thinkest thou to pain thine adversary by it? Know that thou thyself feelest its greatest torments.
Revenge...is like a rolling stone, which, when a man hath forced up a hill, will return upon him with a greater violence, and break those bones whose sinews gave it motion.
