@Setanta,
Killing someone --> a sin --> a breach of ethics
Boinking your neighbor's wife --> a double sin --> a breach of two "ethics"
[how come the ladies get off scott free while I'm, ... ummmm, that guy is headin' for big time heat?]
Adoring other gods --> a sin --> a breach of ethics
Now I can see your point too, Set but I think that I can see it only because of the side of the fence that I'm on. To me, an atheist/agnostic, it's silly even to consider that an all powerful god would worry about someone adoring other gods, ones that I suppose the god knows, don't even exist, so it doesn't seem like a breach of ethics at all. I'm thinking that the two sides hold slightly different views of what 'ethics' entails.
