Ethics and morality are currently mostly subjective. We can form a consensus, though. But instead of the subjective dualities right/wrong and good/evil, I like better pairs like healthy/unhealthy, productive/unproductive, helpful/harmful. These can be objectively measured. Quality of Life can be measured. Mental health can be measured. So we could redefine good and evil to these objective measures and form new standards of morality and ethics that aren't subjective.
