I should not that's not the way things work in Golarion/Pathifnder, that being the intellectual property of Wizards of the Coast...Apparently according to the module Bastion of Broken Souls, angels are not responsible for making souls for babies....Like Deadman almost said, the angels have other things to do than fight against evil. They keep things running, creating the souls for the babies, etc. Evil outsiders ignore that kind of work as it is much easier to steal the ready product.
Thought it would nice to have stats for stork-angels and other humble folk.
Oh man — what if they had to create souls like humans create babies?

Angel 2: "Can't Angel 3 go tonight."
Angel 1: "Not since that blow out last week — Angel 3 needs more recovery time."
