Hitler judged his own morality. Nazis cheered Hitler, and they knew, at some point, that Jews were being tortured to death.
And? Is this supposed to be some sort of condemnation of coming to your own conclusions about various subjects? If so... then try again. Hitler made his bed, and then died while a great many hated him. He made what many of us consider wrong choices, and acted in ways that many of us consider immoral. Normally, people like this are taken down much sooner - before they reach the heights of complete control over an entire country. Hence the reason this doesn't happen all that often. I am not sure why you think this disqualifies any of us from coming to our own conclusions on moral questions. Can you please explain? I am pretty sure you cannot.
Could it be that cheering countrymen should not be the judges of the leaders that they elected?
I have oft thought that pride in one's nation just for the sake of being prideful is loyalty and pride misplaced. Your culture is not "you" - your nation is not "you" - it is basically just happenstance, and is as inconsequential to the core of your being as what clothes you are wearing. So yes, I would judge the supportive actions of Hitler's fellow countrymen as foolish and naive. They should be free to judge anyone as they wish, however, and if their actions step over the line onto alienating or destroying the rights of others, then anyone who doesn't like that behavior can and should go and smack them down. Again - what does this say about our capacity to make moral judgments on our own? Had Hitler's countrymen "deferred to God" for judgment of their leader, what do you think God would have told them? Or would they have to go to The Bible for that sort of "advice", do you think? Would they have been able to properly glean some "answer" from the mostly unrelated words they might find there?
Isn't there an international (or perhaps inter-universe) standard of morality that all most follow?
Not at all. That's a pretty preposterous notion. When you say "all," who do you mean? All
HUMANS in particular? Please just think about that. Because there are other autonomous, sentient creatures on this planet, and many of them have displayed that they don't give one lick of care about humans. Like rats invading human homes, stealing from them, and even getting people sick. Sharks chomping limbs off of people. Flies desecrating our dead bodies by laying their larva in them and eating away at our decaying flesh. Do you seriously think that "all must follow" some moral dictate that is laid out with humans reaping the greatest benefits and receiving the least detriments? Is this
AT ALL how the world or universe appears to work? We decide what is "good" (beneficial) for us and what is "bad" (detrimental) for us. Nothing else cares very much. We're on our own making these decisions. Sure, you can pretend there is some agency out there, pulling the strings - but then you must explain why there are things like parasites, horrible diseases - why you can die by hunger or oxygen deprivation or even lack of sleep.
Is it right to judge ourselves to be right? Or, should we only earn the right to declare ourselves right by the consent and vote of others?
These sorts of systems are all we have. Even The Bible can only be shown to have been WRITTEN BY OTHER PEOPLE - people who apparently wanted to tell us all what to be doing and not be doing. Sure, you can then posit that "God" was the ultimate author - but where is He? We have new and burgeoning moral issues cropping up all the time (like how to treat transgender people), and yet all we have to go by is a thousands of years old text that cannot be updated because "no one has the authority." And yet, do our societies function according to these texts? No... they do not. If you attempted to bring The Bible in as evidence to a court case of any kind, you would be asked to refrain from being an idiot (perhaps not in so many words, but you get the idea - that wouldn't be tolerated or entertained). These texts aren't good enough. They never have been, and they never will be. Hence the reason we continue to discuss any and all moral issues, at length, amongst ourselves... and only the foolish among us point at the books and claim that they contain all the answers.
