This is an "unethical" book which may lead people with "less sensitivity", "narcissism", "jealousy" towards other person to be "abusive" , "destructive". Someone applied these rules to me and nearly made my life absolutely horrible. I think this book should be banned as long as this book leads to horrible consequences to people. An immature might think they are smart gamer but may become destructive. Knowledge of right and wrong needs to be inside a soul. This book neither preaches "that", and a reader might not have "that" knowledge too.
