I think you're addressing a different topic, though. The first topic is, "What determines whether something is true?" The second is, "Are all things that are perceived as helpful by one group universally helpful?" If you hold to a pragmatic theory of truth, these two questions might be related. But if you instead hold to a correspondence theory of truth (as Aristotle did), you can still acknowledge that what is helpful to one person might not be helpful to another. But you would assert that it has nothing fundamental to do with whether something is true or not.
