That means I can kill you or anybody in the world than who cares? Than I should kill scientists, religious and spiritual people, those who believe in the existence of afterlife and in God's existence, because there is no good, evil moral ethics, or whatever is man-made... Since you said there no good or evil tell me the one reason why shouldn't I do it? So, why shouldn't you kill me or everyone else that I mentioned? After all there is no good or evil in the real world, humans obviously had to create those terms otherwise we would all kill each other... Do you see the point here? If moral doesn't exist why don't we just kill ourselves? Of course humans invented moral and ethics, but if you want to be civilized, you had to create those terms and follow them and tell to someone they don't exist, otherwise people would kill each other in whatever country. Saying people are evil doesn't have anything with my belief, it has to do with my experience with other people, and experience to see if the people are good or bad, is more like a scientific research.
