Sleep is for wimps!
In my view there is no universal morality, one which is true at all times and all places, for all people. There never has been, even for those who claim that morality is God-given.
The latter have been no more free of disputes, or of what you and I would call heinous acts, or or selfishness and self-righteousness than the rest of benighted humanity.
Why does it matter what you and I would call heinous acts? It's not like our morality is true at all times and places, and according to their morality they were acting rightly. Besides, why do random collections of atoms have a moral status?
Most of us do have moral opinions, ideas of what is right and what is wrong, how people should act and how they should not act, and of what kind of world we wish to live in. It is much preferable to act in accord with these beliefs than to do otherwise.
It is also true that all choices and all acts have consequences - even though many times these are not predictable and the connections are not direct or even traceable. I prefer our society to others I am familiar with so I try to act in accord with and support its pillars - those choices, rules, acts which I believe constitute its bedrock. I think others do the same. Since circumstances change one must adapt and its not easy to know how...but I do my best and I think many others do the same.
What more do you want?
