Humans are still very much predators, and it is woven strongly into our genes. Science is not even an objective study... it is only about how the forces around US affect US for the most part. For humans, their existence is the sole issue of concern in this world. Therefore, alll things that we label as "evil" are basically just somehow extremely injurious to our peaceful domination of the land. Things are "good" if they promote our continued peaceful and aggressive lifestyle of predation of the land. There is no true "good" or "evil" in nature. Such "ethical" concepts are adopted to suit us in our framing of our collective virtual reality.
