We may try to nudge them, but it's their life. We don't sit in judgment. Most people experience sobriety as liberation. To be a part of that is reward enough. If we were to put sobriety in second place, behind some other goal such as uplifting the human character, we would soon get in a muddle.
Sobriety has little to do with character.
There are addict angels and sober scoundrels. Methods that may work for uplifting the human character may give little traction toward sobriety, and may even work against it. By being there and listening, and offering advice if asked for it, we help each other to deal in a sober way with all kinds of life issues, far beyond basic sobriety skills. If we feel that the Sobriety Priority doesn't meet the full range of our spiritual needs, that's fine. We can go to any number of churches, gurus, or other vendors of enlightenment.
