If morality is subjective...

[Mudhammam]

[bold mine]

Does this mean there is some objective or "not so subjective" morality in every human society? And isn't the emphasised measuring of "pain", "bad" and "evil" a subjective opinion as well? - We could argue all day on what can be considered evil or not, and I'm sure AF members would disagree on the validity of some conducts as immoral or not.

Yes, it's undoubtedly subjective, but given an objective reality from which we all partake and exist in different but equal regions both definite and indefinite, we are governed by certain intuitive instincts evolved through the necessity of survival advantages to dominate. So, for one, we can compare cultures and still judge which fits better with our ideal world, though it is an ideal we can hope to argue for on the basis of human interest alone (in a VERY broad sense), because disinterest in that is akin to a denial of reason for all reason. Many definitions of good depend on fanciful conceptions of teleos, that is, when it doesn't justify its terms on the evidence of experience alone but appeals to some arbitrary but unspecified rule that allows for truly gruesome brutality, as is often the case in bloody political revolutions and religions born on absurd egotism.
