LUHE: "I don't want to take this thread off-topic, but that wouldn't explain infanticide among non-human species."
just playing "devil's advocate" here, since the bible god kills his creation, his "children" and his "sovereignty" adversaries' en masse himself, why would his creation not reflect these 4 wonderful qualities? 1) eagle (wisdom) kicks rivals out of the nest, 2) lion (courage) kills rival offspring. 3) humans, (love) Israel kings killing all male predecessors' children . 4) bull (power) -- bull---!. Divine behaviour assures that only the ferocious survive.
