The problem is that morality can not be messured objectivly as morals change with the times.
The universe works by cause and effect. Statistically once you've learned Quantum Mechanics but those who focus on the exceptions at the atomic level miss the point that cause and effect always works at larger scales.
Ethics is cause and effect written onto human society. Where QM becomes exact to more and more decimal places as sizes grow, ethics still needs learning and understanding to reach that type of certainty.
Morality is a snapshot of the current culture's best effort at ethics.
Morals change with the time because they pursue a goal.
In our lectures we describe perfect character as possible to achieve but impractical to achieve. That's exactly how morality works. Ever working to improve, sometimes sliding back by error.
