Why did a moral god kill Nadad & Abihu?

[Fidel_Castronaut]

Irrelevant (I'm amazed anyone can read into this and make a distinction on the level of punishment against the use of punishment per se).

My point: People have a habit of 'voluntarily' doing something when you have a gun held at their head. Whether you shoot it (cast them into hell) is utterly and entirely irrelevant.

And you have the tenacity to call me disingenuous?

Bad form sir, bad form.

Ah, I see the problem. I wrote "reward if obeyed and punishment if not." You're incorrectly reading it as reward if accepted and punishment if not.

Again, utterly irrelevant.

why would replacing "accepted" with "obey" change the above scenario?

An argument from semantics is a poor one indeed. "Obeyed" &/or "accepted" makes not a jot of difference to the issue at hand: The choice of doing something (either x or y in this case) with a threat of "punishment" (your words) for choosing x over y (obeying or accepting y is the same) is an illusion of choice.
