Sure it can but why follow it?
To live/survive.
Social groups that don't follow some kind of rule of conduct, don't last very long.
It is natural and amoral in nature. That being we are natural and therefore amoral.
That's utter nonsense.
We are natural entities, sure. We are also a social species with traits like empathy.
Morality, is in fact in our very nature.
The natural state of a social species like ours, is to actually care about some form of ethics and morals.
What you say makes zero sense.
You, in fact, only say it because you feel like it validates your fundamentalist religious beliefs. You NEED this nonsense to be true, or else your own religious beliefs don't make any sense.
So you will twist and turn in whatever impossible angle you can think off, just to stick to this silly proposition.
But the fact is, that morality is a human thing. Not a divine, religious thing. It is, in fact, part of the
natural order of being a social animal.
Wolf packs have morals as well, you know (as in: a code of conduct in service of the group) and when they violate these rules, then the other members of the pack turn on him/her.
Wolf justice, if you will.
You like to (or
need to) think that humans are so "out of place" in the animal kingdom and that we are somehow "special" and are submitted to "divine" morals of some sort. The truth however, is that there really isn't anything that special about being a human - as opposed to the rest of the animal kingdom. Sure, we are unique as a species - but then again, so is very species... that's kind of what defines things as seperate species.
Lets not create group fictions which defy objective reality.
Nothing fictional about the natural order and nature of social species.
Nobody outisde would reasonable have to adhere to your group fictions.
Imagine how society would work, if nobody had any moral rules to live upto.
Imagine how your world would look like if everybody could steal, rape and murder without any repercussions. How your world would look like if nobody felt any incentive to be nice to anyone or to help anybody.
You are delusional if you think any group would survive in such circumstances.
As it stands today, you depend on literally more then 1000 people JUST to be able to buy a chicken cheese sandwich at the local store. The farms that made the cheese and all the workers there making that possible. The bank for the loans the farmer / shopkeeper required, and again all the employees there needed to make that happen. The transportation companies that got the chicken and cheese from the farmer to the shop. The traffic logistics you yourself required to get to that store. The car you used to get there, didn't fall out of the sky either.
Imagine a world where you would need to worry about the possibility that any of those people that came in contact with that cheese (the farmers, the packaging, the transport, the shopkeeper), poisoned it - just for the fun of it.
Yes, members of a society have EVERY REASON to uphold some basic moral code as well as a responsability to make sure that the others in the group do the same.
The world would not be livable otherwise. Society would not survive. Society would collapse and die, and humans along with it.
I wonder though, why I took the time to write this. I don't expect it to end up in a productive discussion. More like a dissmissal with some silly one-liner, only to then return to the same nonsense claim that I just thorougly debunked and explained.
