There are surely a few axioms in this universe even though I can't think of any right now. But otherwise I think everything is amatter of interpretation. What people believe is right is right. What people believe is wrong is wrong.
Rape. Rape is wrong. Right? Sure. But if all mankind suddenly went sterile except from a thousand fertile women who refuse to have children, would it still be wrong to force them to bear the seed of mankind further? (Skip the misanthropic crap for a while, will ya?)
Murder. Murder is wrong. Right? Well, I can think up quite a few situations where it would be a good thing.
Stealing. Stealing is wrong. Right? But if you are starving and I have a food war with my pals, would it be immoral of you to sneak in and salvage the leftovers, even if that would require you to unlawfully enter my house and take it against my will? No.
Up. Up is the opposite of down. Right?
Yeah, right. Don't tell me there is a "down" in this universe. There are only directions to and from certain entities, end even that is kinda hard to tell when the gravitational fields intertwine and bend space.
Dark! Dark is the absence of light! Well, per definition, yes. But that definition is a construct. What does dark mean to a species without eyes? The lack of a radiation which is pointless?
And so on. I hereby postulate the thesis that there is no absolute right or wrong, no matter how scientific. Those concepts are all constructs primarily based on human values and depend solely on interpretation.
Anyone disagree?
