[Serious] Moral Obligations toward Possible Worlds

[John 6IX Breezy]

This is philosophical question about if one can be morally obligated to a possible world. One potential solution, would be to treat potential as a kind of existence.

Possibility by it's very nature exists as a plurality. In other words, for one world to be possible so must another. So my question would be, to which of all the possible worlds are we morally obligated to?

ps. As for abortion, my two cents are a amplification of a Thomas Nagel argument: That death is evil insofar as it deprives us of life. Abortion, it follows, deprives a person of the most life possible.
