Holy and unholy *should* be about "good" and "evil" (except in Dom 2, where unholy magics mainly boost death-related powers and holy magics mainly counter unholy). Necromancy is about death, which does not inherently have a good/evil inclination, though the practicioners of necromancy tend to be opportunistic and amoral, hence often "evil". *Unwilling* sacrifices, which is what most blood nations perform, is an "evil" behavior. But since Dom 2 doesn't tag behaviors as "good" nor "evil", holy and unholy have been redefined by the game's designers to revolve around death magics. Since this is so, then holy should also enhance nature (life) and unholy should degrade them, which they at present do not.

Personally, I'd like to see holy/unholy decoupled from life/death and be given more of their own unique powers. I'd mod something along these lines (as well as adjust all blood nations to unholy) except that to my understanding, it's not currently possible to do what I envision with the mod system.
