@hawkeye10,
Firstly, I see a problem with the word "the" in the phrase "the collective", since we are often simultaneously members of different collectives with conflicting allegiances. Indeed, literature often uses such dilemmas as a central theme.
In addition, there are secondary problems with the words "just" and "truth" since these are both subject to contextual negotiation.
In general I suggest the word "duty" is about "living with oneself", bearing in mind that one major view of "self" is that is a product of socialization. Thus the answer (if any) is about
psychological strategies for resolving personal internal conflicts rather than making some general
philosophical statement about ethics or morality.
