I think we know much more about the mechanics of Pathfinder's cosmology than almost anybody in-setting does, and we still don't know a lot and in some.cases have contradiction information about what we do know. Furthermore not even Pharasma knows everything, and with prophecy being broken even what she thought she knew (and what WE think we know about what she thought she knew) is questionable, especially about such murky matters as the distand end of the cosmos. So there's plenty of room for an "ethical necromancer" to simply disagree that what he's doing has some sort of grand cosmic blowback in the long run, and that's if he's even aware of the arguments that it is. And besides, it's not totally clear how necromancy is supposed to hasten the universe's end with what we know anyway. At best we can say it might hasten the end of the planes the Maelstrom is eating away at- planes which some say were created sometime after the universe began anyway, and thus logically are neither essential nor unable to be created again. The Windsong Testaments say the Maelstrom is older than even Pharasma! If the Maelstrom consumes everything else it will still then be feeding into Creation's Forge which produces souls and its own native outsiders and seeds whatever else exists with them, so at least these will still exist, and so will intelligent life. And how does the Void, which seemingly is not even part of this cycle but also creates its own native outsiders and sustains the undead, part of this? What about the Dark Tapestry and the Great Old Ones? Circling back to more immediate concerns, are the undead's temporary delaying of the cycle even really that big of a threat to a universe so large and so long-lasting or is Pharasma just overly paranoid? Even with so many around it certainly doesn't seem like any of the planes are about to collapae due to insufficient soul input- and if they were I'm sure Asmodeus wouldn't hesitate to drop a meteor shower on Geb to sustain the Hells, same with many of the other gods.
I'm sure people will have many different answers to these questions, but my point in saying all this is to say, there's plenty of ambiguity and unknowns here for a necromancer to feel pretty confident he's not doing anything wrong, cosmically, if he's even aware of the implications.
