Just put this person to sleep for a week. Then when he wakes ups and remembers what has happen put him to sleep again until trial date. You just can't change this person for he will look for a new reason why he behaves this way and stick somebody else with same problem with his brand of hate. Otherwise if you can change his heart and live up to the truth this will become a new matter of straightening his life out training reward. Remove hidden hate he has by changing state of mine he become. For this is a hidden health issue for bad thinking and reasoning.

Warning keep him from any kind recall condition of his memory, otherwise this will fail and be back to square one again..
