Well actually, I'm not arguing with you but before the Quincies only killed Hollows in the Human World, as it was stated "Quincy completely extinguish Hollows. Thus the souls that come to the Human World do not return to Soul Society and therefore the souls would increase only on the side of the Human World" we don't really know what happens to the balance when Quincies kill in the Soul Society.
