You continue to make logical errors about science. It's entirely irrelevant whether scientific discoveries are "universal, objective, laws of nature". No way to determine if they actually are and so long as they are repeatable and lead to further accurate predictions they can be hugely valuable.

I doesn't matter whether Einstein's theories of relativity pertain in another galaxy, they work here and make our GPS systems possible.

Nope, still don't believe in an objective psychological standard, and removing psychopaths from society has nothing to do with morality and everything to do with practicality and the protection of state defined rights.

I don't presume to judge right or wrong, only risk and hazard. Proven psychopaths pose an unacceptable risk to others, to society and so must be removed.

You seem to pass judgement on every aspect of other people's lives. Apparently you didn't understand my comment on cancer patients...I don't blame them for contracting the disease, I don't judge them, any more than I judge people suffering from mental illness. It's not my place to judge.

No need to start that silly society you propose, our society already operates on the assumption that morality is not objective and is deeply personal. Our society makes laws on the objective principles of damage to individuals or organizations and violations of personal rights. If you rob a bank and get caught you are tried for damaging the bank and its depositors, for taking their possessions without legal justification. If you punch someone in the face and are convicted of assault you do time for attacking and injuring that person, thus violating their right to personal security. Given that people disagree widely about morality, morality has no place in law.
