This is only sort of the right topic ... but its always seemed to me that so long as those you raise come willingly, then its at least non-black necromancy.
Like say ... an necromancer wizard who runs a city state. His people may never need worry about enlistment into military service, or even do much grunt work. All of that could be done by the spirits of the anscestors and perhaps even those that dared make war against this city.
Now, I ask you, what's wrong with eliminating people's need to work? It could be the beginning of an intellectual golden age.
and if we use Aristotle's nutritive, locomotive, and rational parts of the soul, then most of the time all we really need is to locomotive, depending on interpretations. That means that the rational part of the soul can still kick it in the underworld.
As for intelligent undead .. if someone wants to be a vampire in exchange for some service to the state, is it wrong to allow them to be so, or is it wrong to refuse them?
Wheeh .. Yep, I've got to play my descendent of kings necromancer wizard god-slayer one of these days.
