This is a very ethically question and I am not sure of the exactly correct answer but if it's open to your own answer, I took a course and there was like an answer:
So, to know if a decision or view is "good" the 4 tests of truth can be applied
1. The test of reason (is it reasonable? Can it be logically stated and defended?)
2. The test of the outer world (Is there some external, corroborating evidence to support it?)
3. The test of the inner world (Does it adequately address the "victories, disappointments, blessings, crises, and relationships of our everyday world"?
4. The test of the real world (Are its consequences good or bad when applied in any given cultural context?)
But, as it says, for this - the whole society - the test of the real word would do.
Hope this helps
