This is perhaps one of the worst lies that can be told, and one that very much distorts people's lives. Yes, I very much agree with you that good should be done because it's the right thing to do, not because there is a prize for you.
Morality based on fear of punishment and hope for reward is not morality at all. Doing so is simply self-serving.
Yeah!
I would like to remember one anecdote that my atheist grand-father used to tell. Someone stole something from a priest. The priest said, "I myself will do nothing against my brother. I will, however, tell the Police, and then the Lord Almighty will judge him in the Heavens". My grandfather pointed out the curious double jeopardy here: being judged on Earth, possibly imprisoned, and then the Good Lord demanding that you pay again for the same crime. This is a very curious example of "morals" indeed.
This being a site for Jehovah's witnesses, someone will probably claim that this happened because the person involved was a dirty rotten Catholic. But that's not the case. I bet many a former JW, or acting JW, will recognize that the priest's way of thinking would have fit their own.
Why would it have been wrong for the Lord Almighty to forgive the thief once he came out of jail?
This is perhaps a very common example, but, why is it that a God that created the Canaanites and sent Jesus to save them would not hesitate to have the Israelites kill them to make space, or "Lebensraum"?
My father used to ask me what I would do if I knew that killing someone would spare lots of people a lot of suffering. Would I care more about my own salvation than about my brothers and sisters?
Finally, I would like to point out that the very way the sentence was worded in the Watchtower says I (and Unshackled) are very right. The sentence goes like this:
"A healthy fear of Jehovah strengthens our resolve to be honest".
Which means it was NOT Jehovah that gave us the resolve to be honest, right? The "healthy fear" only "strengthens it", right?
Would anyone even think of claiming that "a healthy fear" of the electric chair "strengthens" the resolve to be honest?
