" I had learned to dwell with pleasure as a beloved daydream on the
thought of the separation of these elements. If each I told myself could be housed in separate identities life would be relieved of all that was unbearable the unjust might go his way delivered from the aspirations and remorse of his more upright twin and the just could walk steadfastly and securely on his upward path doing the good things in which he found his pleasure and no longer exposed to disgrace and penitence by the hands of this extraneous evil. "
― Robert Louis Stevenson , Dr. Jekyll and Mr. Hyde
