Kind of interesting having a conversation about evil and then trying to quantify evil while insisting there isn't a god. I'm not religious, but I also don't believe in evil. When a dog mauls a person, is it evil? When that pet chimpanzee mauled that lady and ate her face off, was it evil? Human beings are animals, just like any other creature on planet Earth. The difference between us and other animals is that our brains are so much more advanced. We can conceptualize, through empathy, something called "evil," or something called "goodness." At the end of the day we're a slave to our internal instincts.... greed, which is really just our natural instincts pushing us to "win." Food, sex, reward. Just like a wolf pack has its alpha dog, humans are driven to dominate, just like a chimps do. Our amazing brains allow us to dwell on these thoughts, while an alpha male chimp wouldn't think twice about destroying a rival, nor would he dwell on it. Our ability to conceptualize our behavior and create deep thought, or, critical thinking, about our actions, in fact "creates" evil, or, rather, our idea of evil and what it means. So, yes, in a very real sense, mankind has created evil, or at least our own definition of our animalistic tendencies, "evil."
