I don't know who the librarian is you talk about, but all the death stuff you talk about is man's creation, in my book. A loving God only requires personal sacrifice for the betterment of the self. So don't get caught up in trying to figure that stuff out because it only distracts you from your personal goal of spiritual advancement. Evil has no bounds, just like love, so do that which makes you love most. Just my 2 cents.
