For the most part I agree with you. Yet, I cannot help but rejoice that he has lived long enough to become a Christian. His repentance does appear genuine.
Son of Sam, David Berkowitz, claimed he heard the devil's voice speaking to him through the next door neighbors dog. Rifkin also claimed to hear voices telling him whether or not to strangle his next victim. A woman named Ameenah Abdus-Salaam had dreams and heard voices' telling her that judgment day was at hand. Dennis Sweeney is another person that lost touch with reality. He suffered from hallucinations, paranoid beliefs, and delusions. Out of the four people I have named only two were acquitted due to reason of insanity. What one jury might consider actions of an insane person, another jury will not.
