The cause of tyranny is hate, the cause of hate is often jealousy of those who haven’t been hated; hence we see clearly, that terrorists, Nazis, radicals, really try to cause not the elimination of whom they hate; but the desire that those whom they are jealous of, should hate; which ironically; using themselves as examples of the injustice in humanity (which they obviously suffered from their own parents or society) they cause people to hate them, and thus win adherents to their cause!
