> I never wanted to do meth because meth tweekers were disgusting and had the lowest social standing. My aversion wasn't from of pro social behavior, it was rooted in self-interest.
Self-interest is not sacrificed for group interest in non-individualistic societies. Rather self-interest and group interest are aligned in such societies.
So, as an example, you didn't want to do meth, but you didn't think it your place to police the tweakers you saw. You didn't see them as a harm to society. And your self-interest was not the same as the interests of society.
