Yes, its a matter of what is best for our species, in an evolutionary sense. It's probably right to say that robbing someone is wrong, but maybe it's a question of where one path leads us as a species as opposed to the other path. It's not bad to question what you have been taught is right and wrong. Maybe more murder and fewer people will be better for the species as a whole when you think about limited resources on this planet, resources that are being consumed and not replenished at an astounding rate. Of course, murder is probably not the best solution to problem. Do we really want 10 billion, 20 billion people on this one planet that we are currently limited to. Limited to for the forseeable future. Is it right to have as many kids as you want, or is it wrong to overpopulate a planet that is quickly being consumed? Question away.
