Just answer the question.

You can put aside your whip. This is a discussion forum, not an interrogation.

I said to Bedfellow that the question is unclear on the starting points. If you have a deductive argument, conclusions will differ, depending on the starting points.

Okay, I'll take a shot at getting an answer.

Would you behave differently if you were certain there existed no externally-originating consequences or rewards for your actions towards others? E.g., would you kill others for their money if you were sure that you could get away with it, escaping negative judgement and punishment even in the eyes of whatever supernatural powers exist?

Me, I wouldn't. But that's just me. I don't think it's a moral thing to do.
