The individuals were not pontificating as to the existence of a God. They were merely expressing their distress/ empathy/ feelings in their own various different ways. If that involves religion in some shape or form then so be it. Some smart Alec then took it upon himself to castigate them and make light of the matter. People dead and property destroyed, and lives ruined, "For the love of God."
Catch a grip. Be grateful it isn't you or your families picking up the pieces.
