The simple truth which explains the insanity of sadism, barbarism and anti-semitism, radicalism, and bullying is that when we God-forbid develop an ego, which is the subconscious belief that "we are the best!" and just like if the star of a show was suddenly challenged by another outshining star, and sensing that this person is taking away "what is rightfully yours…", so just as you may become angry and even violent if somebody were to steal something precious of yours, similarly, the ego becomes angry and violent; but this anger and violence becomes self-justified by the brain, finding "evil" in the other, that in the brain’s estimation, deserves to be eliminated!
