[Serious] Moral Obligations toward Possible Worlds

[Anomalocaris]

Maximally good, as defined in utilitarian philosophy, is the most good for the most people.  Inasmuch as the involuntary labor of some small number supported the greater number, it's a utilitarian good.  It's one strategy for securing necessary labor.

Is a extremely large amount of good for fewer people less maximally good than a tiny amount of good for more people?

What is good?  What if to some people, good IS the harm to others?

It seems the key to workable, not just agreeable, utilitarianism must be reliance to some degree on some higher good beyond the individual good according to how each sees it.
