Ugh, guys I knew what it all is, I was trying to get thehunter to say it :facepalm:
Any who, I still think too many people here need to be more open minded with necromancy. First off, it is legal throughout the empire, save for some areas (Morrowind, Summerset, and Valenwood). Breton nobles are rumored to have sanctioned necromancy in order to scare bandits, the empire employs necromancers and even donates fresh bodies, and the khajiit really don't give a damn.
Of the books about necromancy, I haven't seen where souls are used as ingredients to reanimate dead bodies. The only in-depth source doesn't even mention soul gems, only magic.
You're pulling souls from their afterlife. That is evil.
The dunmer do it naturally, but they're not considered evil, sometimes holy.
It subverts the natural law that is established by Arkay. And he gets to dictate it because his being is wrapped up in that part of reality.
No one likes Arkay. And if his law was natural, dead bodies couldn't be reanimated in the first place. Plus, it's just a pile of flesh that only looks like your dead grandmother, it's not her anymore.
