A well-known quote from Mark Twain appeared on my Tumblr dashboard today:
But who prays for Satan? Who, in eighteen centuries, has had the common humanity to pray for the one sinner that needed it most?
Many use this as a quote to foster atheistic belief, but I see this as being quite applicable to the psychopath as well. Not that praying would help save society from those that are antisocial, but in that society does not think of rehabilitating the antisocial, merely condemning and punishing. With the modern prison system, society tries to forget what they fear.
