This is a theoretical question, in reality I don't even like cleaning trout. The point is that the assertions of believers are impossible to ascertain as none of us is a mind-reader. Doesn't that mean that transparent, codified secular law is more practical and for that matter more ethical than religious motivations? Discuss!
Just remember this: Anyone claiming to have an inside track to the mind of a creator of the entire freaking universe should be viewed with extreme suspicion and derision.
