In my opinion, all of your arguments for real world relative morality are only valid IFF (IFF means if and only if, btw) The Athiests have it right and anyone who believes in a god is wrong.


Now, in Cf, this doesn't count, because it is fairly obvious that Dieties exist and that they set a definite morality of "this is good and this is evil".


but, in the real world, I would say it is only valid to say "Labeling someone with alignment is rather artificial, and should be regarded with suspicion in real world. " like you did, only if you believe that there is no God who has said "Doing this is good, doing that is evil, period".


Most people on planet earth, not being athiests, might disagree with you that it is invalid or artificial to call anyone "evil" or "good", but you're good to believe what you want on that score.

Even in your example, it comes down to "Why is killing evil" the athiestic view has something to do with the greater health and survivability of the species or something, the religious view is basically "Because God said so, that's why"


*disclaimer* I know there are some religions out there that DO hold the idea of relative morality, let's ignore those tiny factions for the sake of my argument *smile*
