The UBA's of the world, past and present seem to come from a space of objective observation. A place of "what works and what doesn't work".
For example...
...
Let's say that there a 3 people sitting around a table: Jesus, Buddha and Hitler. Then we ask Jesus and Buddha to give us an observation of Hitler. I choose to believe that they would respond this way:
Jesus - "He knows not what he does."
Buddha - "He is asleep."
I believe they transcend morality and look at what works, individually and collectively. If it is our goal to be peaceful, loving, kind, understanding, compassionate then the actions of someone like Hitler would not work to obtain that goal. If our goal is to suffer, create pain, kill, be judgmental, separate ourselves from others then Hitler's actions would work.
It is always PERSPECTIVE and how we see things. Where are we coming from and where are we going.
The picture below illustrates that there is no right or wrong. Instead it illustrates COMPASSION, UNDERSTANDING, EQUALITY, and NONJUDGMENT. I believe that EVERYONE wants peace, but in many ways we are IGNORANT on how to obtain it. So we go looking outside of ourselves to find it. This rarely works. We say "MY WAY IS THE RIGHT AND ONLY WAY!" and that does not work either. FORCED INCLUSION IS ABSOLUTISM. Yet we seem to always adjust our morals to work for us. Adding footnotes to things like the 10 commandments. Saying something is a sin or wrong until that experience hits close to home and then rationalizing (rationing lies) our adjustments in our morals.
"Thoroughly unprepared, we take the step into the afternoon of life. Worse still, we take this step with the false presupposition that our truths and our ideals will serve us as hitherto. But we cannot live the afternoon of life according to the program of life’s morning, for what was great in the morning will be little at evening and what in the morning was true, at evening will have become a lie.” - Carl Gustav Jung
