You have a funny understanding of good and evil - if it's useful than it's neither good or evil.... (Yes we are taling about different set of morals, but that doesn't matter)
Untrue, torture is useful to interrogation yet considered evil by most. Friendship and love is useful for binding alliances, yet considered good.
And yes, I'd prefer more neutral, less hated god than Nocteclaw becase of the exactly same reason why I don't want necromancy: That will get us more enemies and fewer allies
Nocteclaw is diminished and out of sight, out of mind for the vast majority of the "good" races. We are unlikely to garner significant enemies as a result of our unpublicized affiliation and patronage of It. The only ones who still seem remotely aware of him are potential allies, the merfolk. Thus does Nocteclaw bring us only gain.
Some possible allies
1) Trees
2) Animals (We may choose a druid route easily... just protect forests from... elves. Isn't that ironic? We got two loyal trainers that can train us empathies to a nice level)
3) Other night creatures
4) Night creature empaths.
5) Humans that want to end elven domination
6) Various animal people (they are discriminated heavily by civilized races)
7) Various gods and their followers
Maaaaybe dwarves
9) Merfolk
Other night creatures would likely be indifferent or supportive of Necromancy.
Dwarves are lawful good, and are unlikely to join with us regardless of the circumsances.
Merfolk are likely to ally with us already, as aforementioned as a result of Nocteclaw.
Trees are unlikely to care about Necromancy, nor are animals, so long as we don't harm either group with our creations.
Necromancy make it harder to cooperate with all that groups
Necromancy make us less acceptable for some future consorts (and we don't know opinions of current on that matter)
Regarding consorts, see the above statement about night creatures. I'm sure they would not consider feasting on elven flesh before their transformation either.
I respect your opinions, but you might be projecting your beliefs onto the npc's. This is a permadeath game with consequences and no redo's, I'm simply trying to use every avenue of power at our disposal.
However, in deference to the detractors of such a course of action, I would advocate that if we do learn and subsequently use Necromancy, we save our minions for guarding our key strongholds and/or when we direly need the support, so as not to incite more npc's to strike against our cause.
As for how to learn it, next time we see Foghorn we can ask about it. Alright, I said my piece and shan't argue any more about it. Sithis forbid this turn into the new version of the alice debate...
