>social obligationThe first four words have strong emotional connotations, which is why they give off a vaguely similar air to that of sentimentalist literature, whereas the last one implies a set of social normativity and a sense of having a compromise to certain set of rules that is very typical of 18th/19th century moral discourse and treatments of socially acceptable behavior, but that would nowadays come off as overly formal. Nowadays, one rarely hears a word pairing like "social obligation" when talking about promises made to friends or esteemed family members. Instead, it would be more common to expect a corporation or a civil servant to have a "social obligation".
