There is dangerous point at which anger ceases to be an emotion and becomes a driving force. A person bent on revenge moves unknowingly further and further away from being able to forgive, for to be without the anger is to be without a source of energy.
Hatred is the rabid dog that turns on its owner.
Revenge is the raging fire that consumes the arsonist.
Mercy is the choice that can set them all free.
