I would think that many would view the act that reanimating the dead and enslaving their souls would be considered evil. I'm guessing that most necromancers raid tombs and practice their art on the innocent, although personally I have no problems on reanimating a bandit I just killed and forcing him to wipe out the rest of the camp. It seems to be no different that using illusion magic.
As for if they really conjure the soul back into the body, several in game books and events in Skyrim say or imply yes. Here are three examples that I found.
http://uesp.net/wiki/Lore:Arkay_the_Enemy
http://uesp.net/wiki/Lore:Blasphemous_Revenants
http://uesp.net/wiki/Lore:Ancestors_and_the_Dunmer (this book has a lot on necromancy/souls/death, although I guess you could argue its validity)
There are a few necromancer related side quests in Skyrim. One of them (I don't remember the name) invovled you going into some nordic tomb and a woman was trying to resurrect her husband by using someone else's body (Holgeir). She failed this, and reanimated Holgeir and his wife(?) Fjori. Upon completing the quest, you free their spirits and they reward you for it. There is also the Blood on the Ice quest in which the necromancer Calixto is trying to bring his sister's soul back to the mortal world. However, unlike the previous quest, Calixto tries to use parts from many different bodies to do this. Unfortuantely you don't know if he'll be successful or not, but I think his chances are higher. After reading Ancestors and the Dunmer, it seems like a person's remains acts as a beacon for the soul to contact the mortal realm. The woman in the first quest failed because Holgeir's spirt was too strongly connected with his remains, while Calixto may have had a better chance since there isn't just one spirit connected with the body.
There was also the quest where necromancers tried to resurrect Potema, and although the player stops them, her spirit is still connect to her remains and at the end of the second quest, her remains are blessed by Arkay which should prevent anyone else from trying to bring her back to the mortal realm. Then there was the quest with the necromancer/philiac who reanimated bodies of woman, and managed to conjure up their ghost, which seems to be more or less like their actual spirit or soul. Again, their remains probably just acted as some sort of beacon to summon their souls. I also think that there is another quest in Skyrim in which a Nord talks about a Dunmer necromancer enslaving his ancestors...
I would also say that black soul gems are also within the field of necromancy. They too appear to be more or less evil according to the Ancestors and the Dunmer book, as it states that souls who were unwillingly bound to weapons go mad.
You could question all of the validity of these sources, but I have yet to stumble upon any good piece of information that indicates that you can reanimate a corpse without summoning its soul. The only thing that suggests this would be bethesda's gameplay mechanics, as the undead conjured in oblivion (and in morrowind too? ) had white souls. In Skyrim you can reanimate undead that you soul trapped, but you can't soul trap your reanimations. However, gameplay mechanics does not define lore.
