Nigel has a moral obligation to keep his promise - but why does he?

 That Nigel has a moral obligation how is this claim true?

And what is it about our 'world' that makes it true?

Excluding inhuman monstrosities like Putin's invasion of Ukraine

Is day to day moral strictures no more than social hygiene? 

So what kind of people are quick to employ the

moral argument? in the view of many it is 

compromised politicians like Pelosi and Joe Biden

(practising Catholics both)   who are prone to 

employ the simplistic/stupid moral argument.

Pelosi/Biden 'Moral' claims are not actually in the business of reporting facts, but their cynical way of controlling others behavior 

As many would argue, it is a is a mistake to think of moral claims as true.
