If I was offered the chance to get a million dollars(or whatever is most valuable to you, maybe you get a 1st class honours degree, a high paid job,a loving wife, the ability to have children when you were barren,another day with a deceased loved one etc), all I had to do is press a red button and I would recieve my wish, but instantly a child in China, who would have otherwise lived, dies. There are no consequences, in the sense that it is untraceble, garanteed, and no prison sentance or punishment etc, you do not know who the child was, so you have no emotional losses.
If you were completley convinced of an atheistic viewpoint, no afterlife, no God, that the universe is big cosmic accident, etc etc,
should you press the red button?
The only issue you could possibly have is guilt in this life.
But from this atheistic viewpoint is guilt not simply just a social construction imposed on you, by your unpbringing, by western societies current viewpoints (just like years ago, you would have felt guilt for pre marital sex, if you were immersed in a fully christian fundamentalist society etc), just a kind of moral relativism.
So reducing morality to this, should you not then simply transcend it, and discard it completely?
