You piqued my curiosity here.

I'd never really put the consequences of my actions under the microscope of this level of scrutiny.

Anyway, since we've come this far and we agree that others (especially our successors) likely won't feel bound by my logic or yours, then I'll admit that don't get very excited by discussing the limits of moral relativism either, since it feels a bit like playing a lose-lose game.

Self-examination, discernment, compassion, charity, understanding, the list can go on ... are principles of morality, besides the golden rule, that might be solid ground to stand on. (I am not sure how much these differ across the spectrum of belief systems.) I think if I am true to these, then how much does it really profit me to concern myself with the disapproval of my successors?

Over time our starting premises seems to change more than the logic itself.
