i get what you are saying, i don't know about if one has more soul than the other but i believe everything has some sort of consciousness, even inanimate objects and i believe we are all on a quest to turn our darkness to light. Ursula le guin in her novel the left hand of darkness mentions that darkness and light both need each other to survive. that everything in this world has originated from a chaos of darkness and goes towards the light (salvation) and this is how consciousness is developed and how transformation occurs. there are hidden rules to this universe and if you know them you can gather more soul or energy for yourself. soul as consciousness has an imprinted set of information and when someone takes away your "soul", they take your power or in other words the wisdom you gathered through all your reincarnations.
