if we had a universal standard for good/bad or right/wrong would that heal the great divide among us? What are the odds of that occurring?

Look at the world around you. Humanity is incapable of establishing a "universal" standard for good and right and the odds of that ever happening at the hands of humanity are zero. On the other hand, humanity is very adept at establishing a "universal" standard for bad and wrong. Only my opinion of course.
