If "we" live by the Golden Rule then our conscience is clear. At least we know that we are doing our best in the eyes of God... and for ourselves.

We can live the example, but we can't make others follow our example. If others don't do their best, then it's their problem. If we think that others aren't doing their best, then we are judging others. That's not our job, it's God's job. Our job is to be as caring and understanding as we can be but we don't have to keep butting our heads against the same brick wall until we're bloodied.
