That's because a lion is alive and a fetus is not. Your choice to call it an unborn child is propaganda only. You think the bible treats fetuses the same as humans? How come the old testament penalty for a fetal loss was entirely different than a human loss? Because even 2500 years ago those primitive cultures understood it ain't a baby until it is born at which time it is entitled to the protections given humans. So God says so and that's good enough for me.
