I answered this on Quora:
Absolutely none.
The threat of hell is a reification of standard human legal systems. There are laws, and people who violate these laws are taken by force to prisons, where they are to suffer.
The notion of hell is the same thing, with an imaginary cop, and based on PURE BLUFF. In poker, we call that a ‘naked bluff’; when you have a really poor hand, but you make a big bet anyway.
Some of us have called that bluff, and they have showed a pair of fours, at best.
I can understand why rulers, and those who have truly been absorbed into social norms want everyone to buy into this, and fold. The fact is, getting away with a lot of criminal activity is easy, if you have any brains about it.
I’ve heard variations of, “but, if you don’t believe in hell, and you can avoid detection by human authorities, you could kill me without being worried about being punished!”
That’s right. Don’t piss me off.
