David I think a child can be taught or given the bounds of morality (a conscience) by age 8-10. Morality absolutes vary with the society one lives in. Dealing with sociopaths and psychopaths tell us some folks are not capable of a sense of morality.-I think a child can be taught there are colours at a very young age. I think a child in their mid teens can be taught colour is literally a figment of their imagination.-The fact you say Morality absolutes vary with the society is an oxymoron.-At best it is societal or cultural morality.-I think in practice what I think is right is pragmatically indistinguishable from what I want.
