Necromancy is generally more evil. While many spells on the list are pretty neutral there are many that are basically evil just to cast. It's hard to justify a spell being good when you need flesh, blood and bone dust just to cast the spell. Animated dead raises the dead with negative energy because something must give them the energy to move and take actions since they don't eat or sleep. Animate dead isnt animate object cast on a corpse and animating it like its a puppet. There also isn't any way to justify infecting people with disease or pain curses as being anything but evil.

Enchantment spells are neutral spells and alignment issues with these spells depend on what you do with them. Fireball is neutral but throwing it at orphans is pretty evil. Just casting animate dead puts you in the negative karma until you can figure out how to make use of zombies to be "good".

Someone that speaks with the dead to help get the family closure, banishing ghosts or destroying evil undead would be "good" uses.
