Beyond a shadow of a doubt, all human behavior is as Kabbalah teaches from one of three organs/operating systems, which can access the hardware, namely, our thoughts speech and actions – from regular to ideal to disaster – depending if your society is a mature one (namely, in which people have sublimated in the past their desires for ideals) we are born primarily as an animal, with instincts (heart) these emotions drive us towards what will feel good and away from what will feel bad (sex, drugs being a good example) on the other hand, we will role-model after our elders and hopefully if educated, we will also learn that there are positive and negative behaviors, and then life will be a constant battle between our mind (OS2) and our instincts (OS1 – dieting being a good example) but unfortunately, the story gets far darker, for lurking in the dungeon of our psyche, is our ego, a demon capable of all the evil man has ever committed which seeks superiority – and conversely, as we see in the case of Islamic terrorism, as in Nazi Germany, has a psychopathic drive to torture, avenging “hurt” ego
