[Parts of that are a little questionable, but...whatever. Brain food.]
I suppose that depends on what exactly you mean by a soul. I don't know how this world handles it, but I've always understood there to be parts of me - and of all people, man or monsterkind - which doesn't exist in a strictly physical sense. A person's identity, which remains if their body is altered...memories are a piece of that. Essential nature is another. So the soul of an entity would be the aspect of it which is aware and willful, the part that desires and resolves to act.
