You were comparing two things.
1) The roundness or flatness of the earth.
2) The rightness or wrongness of killing. — charleton
By 'they' I assume you mean definitions of morality in common usage? Haidt and Graham for example identify five common threads; Care, Fairness, Loyalty, Authority, and Sanctity, but others such a Bernard Gert list them as avoiding being the cause of death, pain, disability, loss of freedom, loss of pleasure, in that order (i.e, you might unavoidably be the cause of the later ones on the the list in order to avoid being the cause of the earlier ones). — Pseudonym
Murder is principally wrong because it goes against the nature of life itself. This can't be demonstrated as if it was a scientific fact, but can be demonstrated on other ways. Doesn't the fact that societies around the globe progressively traveled from allowing killing in many situations towards universal ban on killing tell you something? — Dalibor
What is the reason for labeling this group of acts as morally right? — SonJnana
It's not your assertion that "murder of innocents is wrong" derives from the values of a particular society that I object to, It's your assertion that this is in some way categorically different from "the earth is flat", which, in exactly the same way, derives from a particular society's opinion about what 'flat' means. Neither come from some outside source, but neither are entirely subjective either, anyone trying to argue that a ball was flat could be countered by showing that a ball is unlike all the other things which we agree are flat; someone trying to argue that murder was good could be countered by showing how murder is unlike all the other things we call good. — Pseudonym
