Emotion and outrage are fine up to a point. McDonald makes a meal about the terrorists being inherently evil. What is done is done for the love of killing and the sadistic satisfaction it gives this breed of men'. McDonald is dead wrong. This is an historical problem, not simply a few blood-thirsty Arabs on a one night rampage.
Every human being is endowed with positive and negative energy.
When life's expectations are cruelly denied because people are consistently oppressed and unfaired, negative forces surface and predominate and revenge seems to be an instant response. Satan, the well-spring of all evil, was an angel who challenged God and was rejected from Eden. In revenge, he stained the world with everlasting sin and death. Satan lives within each and every one of us regardless of our skin colour. The human capacity for good and evil has been widely acknowledged.
