Fill his spare time with violent music and violent video games. Remove any sense of final judgment, morality or responsibility for his own actions. Remove any sense of respect for the sanctity of human life. Instill in him a sense of I, My, Me the view that self is the single most important thing in life. Instill in him a sense of materialism and consumerism.
Life is a game.
The one with the most toys at the end, wins. Then label him a failure for being different or not measuring up. Make him feel left out Make him feel the need for 15 minutes of fame. Make him want to do something, anything, for recognition. Then stand back and wait for the inevitable.
