So if mankind can't do it, who?
God, for one.
There are a number of moral athiests out there, but even they tend to have moral ideas that are rooted in faith.
But to answer what I think your question is, how about this-
We have government because it's a necessary evil. I don't think we need more of it. I think we have far too much. But I also don't think we could get by on as little as the 'L'ibertarians would like. Freedom without discipline is anarchy.
That's one. "for one" assumes others. They are????
And who will tell what God wants? Let me know because there is much disagreement among believers much less non-believers.

An oxymoron.
We have government because it's a necessary evil.
True, but it need not be evil. It's just that it always has become evil.
I don't think we need more of it. I think we have far too much.
Me too.
But I also don't think we could get by on as little as the 'L'ibertarians would like.
A matter of opinion, but I perfer small L libertarians on that.
Freedom without discipline is anarchy.
True. Governments in a free society exist to defend the rights of the individuals in the society. That is the discipline. The larger problem has been disciplining the governments, not the people.
A government that only defended rights wouldn't be evil, it would be a force for good.
