Honestly, in this discussion, it's a distinction without a difference. If the Endless need to be powered by a thing that can only be gotten from people when they die, does it really matter if the thing they're being powered by is souls, 'corporeal aether', blood, or any other substance?

The Endless are powered by life force/corporeal aether. The regulators are powered by souls. Both of them come from people dying, and Sphene was willing to kill the entire world outside that dome to solve the supply shortage the Endless were causing. A 'well actually' on what substance that is doesn't change a nick of the scenario.
