Solomon turned to wisdom and madness and folly (Eccl 2.12). That was never going to end well.
We need standards, a plumb line, a line drawn in the sand. When leaders, especially, do not live by righteous standards then chaos follows.
Observing world affairs; it has to be said that the standards of many prominent leaders fall far short of any reasonable standard. For example, I read recently, that Donald Trump spoke in excess of 30,000 untruths whilst in office as President. That level of persistent falsehood is extremely damaging to any society. Others pursue wrong-doing in other ways.
Significantly, the book of Ecclesiastes, which I quoted above, concludes by reminding us that we are accountable to God who is righteous and true and good.
