Re: recognizing morals, the human mind is capable of amazing feats of compartmentalization (a flaw that cults like the JWs take ready advantage of). Remember that, in his video confession, Evans defended himself by stating that he had not committed murder or rape. Which is to say, he redefined what a "MORAL PERSON" is, to ensure that he was still a MORAL PERSON even after admitting to behavior that most people agree is clearly immoral.
And then he, MORAL PERSON that he is, can persist in expressing disgust and judgment towards others for actions that are far less egregious than his own. The grifter's first target is always himself.
