Hello all, I was wondering your opinions on the subject of morality.

Do you think that right and wrong (morality) is
subjective, and
relative?
If everyone is doing it, does that make it right? And if no one is doing it, does that make it wrong?
And if nobody sees you doing something hateful, and you aren't caught, were you still wrong? Is the only thing wrong getting caught?
If society taught us that [any hating act] was right, would it be right? And if society taught us that [any loving act] was wrong, would it be wrong? Why/why not?

Here's a good question:
What if Hitler had won World War 2, taken over the world, and brainwashed everybody on earth into believing it was right to murder innocent Jewish men, women, and children. Would that belief then be "right,"
or would everyone on earth be "wrong"?

Or is it
absolute? Are there laws that are above the laws, ones that governments and nations and all people regardless of anything should follow?

Or is it
situational? Is there a time when killing innocent people is OK, stealing is OK, raping is OK, etc. What about wartime? Is that an exception, or has everyone just been taught to believe it's normal and OK? That's a tough one for me, because it sure seems that there are times when war must be waged, like during the Holocaust in WWII.
What do you all think
