Well, the uncertainty principle says that you by observing and measuring things, you neccessarily change the outcome. I'm saying that by reading the bible, it's impossible to avoid changing it in some way. So they're similar ideas, although the uncertainty principle is more precise.
I'd say that dishonesty isn't a form of suffering, it just causes suffering. Cheating on a test gives the other students a lower ranking, and makes you feel guilty. So you can pretty much "derive" the concept of honesty from the suffering rule.
Not believing in Jesus, however, doesn't cause suffering, at least in general. There are entire countries where very few people are christian. It's a bit far fetched, not to mention offensive, to claim that everyone in these countries is suffering from their lack of belief in Jesus.
But are there any atheist systems that are not based on the problem-of-pain? I mean do they disbelieve based on anything but that reason? I don't mean "Because-that-is-the-way-it-is and anyone-who-disagrees-is-stupid"?
I can't speak for all atheists, this is just my own thinking. My own code of ethics derives from the assumption that suffering is wrong. I would still know the difference between right and wrong even without the derivation, because of my upbringing and my evolutionary instinct. The code of ethics just makes it more complete, and (hopefully) ensures that I can't be tricked into doing the wrong thing, because I know my logic is sound.
Incidentally, pain isn't the same as suffering. Pain is the minds way of telling you not to walk into walls or eat yourself. Suffering could be defined as undeserved pain (and similar emotions), that has no overall benefit to us. For instance, being born in a cage, living out your life in it, then being eaten is suffering.
One reason I don't believe in God is that I don't think his existence would make any difference, either to me or the world around me. I would try to be a good person regardless of heaven or hell. I'm happy regardless of how much Jesus loves me. The ways of God are not only mysterious, they're statistically random, so if you pray to roll a 6, the chance of God answering your prayers is exactly 1 in 6. If God existed, it would be as if the whole universe, including myself, had jumped a meter to the left.
