So morality is little more than expediency...?<quoted text>
Did you mean neurons? There are times when some species consider it okay, and in the wilds there will always be a call for such. But we are no longer in the wilds, so we adapt our morals to the new environment. There is more value to saving all lives, for each human will have a skill set that when put to proper use will benefit us all.
If it is just expediency, how can you argue it is right or wrong?
You are being inconsistent.
So why would anyone accept your irrational position as having any value?
