Lets not forget that good and evil are creations of man to give rason to anyone event that happens. it's a concept that only we can understand. Good and Evil is a concept created by the human mind. What people do are not good and bad they're trying to make a living or survive if you want to get down to it. In some cases to survive you need power. POwer to rule a people, a country or the world. Nothing is good or Evil it just is. Nad trying to break donw to weather the soul or DNA is the source of evil is a superfical matter. Evil and good do not exist. They are concepts, and thoughts. All things in this world exists diffrently to each life form. So in turn concepts will differ as well. so good and evil being a concept will be very diffrent as you go down the chain of life on this planet. But you reach a point were good and evil no longer exist. It become "I'm alive or dead". So good and evil are just a cover for life and death. Thats my take on it.
