How to measure the size of one's soul? It is measured by inches and feet, or ounces and pounds? Perhaps one can be measured by its acts, kind or cruel. Who would believe you if you were to tell them the weight of your soul? If it were at all possible to quantify our spirits, would that put a value on them?
If valued, then able to be bartered? If bartered, then marketed? If marketed, then increased demand for greater souls? With increased demand comes increased supply. Imagine of glut of souls available on the secondary market. What happens when the supply of a product far outpaces its demand? The value of that product shrinks, easy to get anywhere. No one wants it anymore. Unwanted souls, discarded and ignored.
No. Our souls are not weighted, nor are they measured. Each is priceless beyond recognition. We should not lose them so easily when another has sacrificed all for our right to keep them.
