Is it wrong to kill a human being?
Most people, darwinian atheists included, would say, "yes". Although, push come to shove, the best reason they could probably come up with is because humans' chances for survival are greater if we don't kill one another.
But let's consider this. Is it wrong for, say, a bear to kill a human being? Would we say that the bear was immoral, or committed an act of immorality, or that there was right and wrong behavior for a bear, and this was wrong? Probably not. Why? Because bears are not moral creatures, they do not have a moral sense, they act purely from instinct. And so, it would not be wrong for a bear to kill a human.
Why then is it wrong for a human to kill another human? Not because it's intrinsically wrong (as we demonstrated with the bear), but because we have a moral sense, and it would be a violation of this moral sense.
But where did this moral sense come from? Evolutionists claim "it just happened"; it's a product of mindless, uncaring evolution. If that's the case it's really just a con. If killing a human is wrong only because it violates our moral sense, and this moral sense is the product of mindless evolution, then, get over it, one person killing another human being is no more morally wrong than a bear killing a human.
Unless a moral God created us and embedded within us a moral sense and moral behaviour is an objective reality and not just the collision of mindless atoms inside our evolved brains somehow tricking us into thinking that something called morality really exists.
Consider the flip-side. If moral sense developed from mindless, uncaring evolution, and the highest goal, a la Darwin, is survival, and killing another human being is wrong only because it lessens our chances for survival, then what if it could be demonstrated that killing some people, say the old, the infirm, the defective, the sterile, non-breeders, etc. would further optimize our chances of survival? Knowing nature's plan -- reproduction and survival of the fittest -- would it not be OK to override our defective ingrained morality and, taking our cue from what we think we know about nature's highest goal, kill other humans? If not, why not?
So, let me ask the question. Is it wrong to kill?
