I think what you meant to say instead of "anything goes", was lack of duty.
That's what seems to be missing, that organized religion did bring to the table.
Duty.
The duty of the teacher to protect the student from bullying? Gone.
The duty of the parent to stay in an unfulfilling relationship for the sake of the children.
The duty of the professional (cop? doctor?) to serve and protect the public.
The duty of the prosecutors to enforce the written rules.
The duty of the politician to send our soldier-youths into just wars.
It was religious adherents who dispensed with that 'duty', not atheist reformers. Jesus himself said that you should not cast stones unless you are without sin (nobody is, therefore nobody may cast stones.) Jesus brought this and other reforms to the jewish religion and was murdered for it.
The same religious adherents told slaves to be obedient to their masters, even when their masters were monsters, so let's not give them too much credit.
Duty.
The duty of the teacher to protect the student from bullying? Gone.
The duty of the parent to stay in an unfulfilling relationship for the sake of the children.
The duty of the professional (cop? doctor?) to serve and protect the public.
The duty of the prosecutors to enforce the written rules.
The duty of the politician to send our soldier-youths into just wars.
And on and on.
