The spell, in Spell Compendium, mentions the "Animating spirit must be free and willing to return". The spell also specifically mentions using the spell to bring back skeletons and zombies. So first, for the sake of argument, is there any person would would willingly give up the afterlife for animating a completely non-intelligent creature, forced to follow the orders of the person who, presumably, killed them in the first place? A similar but less strong argument could be made for other kinds of intelligent undead. Since I think this interpretation of the clause would lead to a rather silly spell, I wonder if the "Animating Spirit" has the same intelligence as the undead that was destroyed, so non-intelligent types would be willing by default, and intelligent types would be compelled by their service to the necromancer who created them?
