poke: cultures differ in the moralities that they affirm and this does lead to substantially different behaviors such as honor killings. Moral reflection has historically been one cause, along with economic selection, noise due to charismatic genius, cultural admixture and others, of changes within a culture in what morality it affirms. That moral reflection is mostly done by people with a concept space that contains morality as a concept and the reflection would probably follow different (I'd guess mostly 'better' in the sense of moving towards more stable states faster, but it might not have happened at all) dynamics if the same people had done it without a concept of morality.
