Some Live, Some Die. Why?

Brother Juniper [in "The Bridge of San Luis Rey"] considered three possible explanations for the deaths: The victims were in the wrong place at the wrong time (a heretical interpretation he immediately rejected); God was punishing the wicked for their sins; or angels were being called early to heaven. Either humans are "like the flies that boys kill on a summer day" or they're like sparrows "who do not lose a feather that has not been brushed away by the finger of God." (Cynthia Crossen writing in The Wall Street Journal about why some people died and others lived in the Minneapolis bridge collapse).
