I just can't come to acceptance on the replies saying "animal cruelty was ok back then but it is not".
Remember: lions eat baby gazelles, sharks tear apart baby dolphins, plants eat flies. Robins eat worms, hawks eat robins. And after a fashion, God kills everything and everyone.
This place is not the final destination for anything that breathes, so the nasty business of getting dead, while certainly harrowing to contemplate, is not the last chapter of the story.
God made human childbirth much more hellish and dangerous for the human mother than the births of virtually any other animals. The human head is really much too big for the birth canal, and is squished down to a pulp, traumatizing the child in childbirth - and the huge size of the human head essentially causes the baby to rip its way out of the human birth canal. Human birth is very bloody, horrible, leaves the mother utterly wiped out and helpless for a bit, and in days before medicine, resulted in death of the child or mother or both about 10% of the time.
And that is by God's DESIGN!
There's a lot of suffering while we're in the flesh. True for us, and for the animals.
And in truth, all of that suffering is by God's design. For "not a sparrow falls with the father's consent". We call natural disasters "Acts of God", and that is literally true. When a wall of mud, unleashed by a hurricane, buries an orphanage in the Philippines and crushes and suffocates 40 8-year olds, that is actually God's hand.
If their terrible deaths were the end of everything, then God would be pretty monstrous. But actually, their deaths are just a harvest, and they go on after death, as living spirits.
The same is true, probably, of pigs and birds and cows and fish and every other animal that is killed, maimed and died, or is devoured whole by another animal. It's grim business, this harvest of death. But so is being born. So is cutting molars. A caterpillar essentially digests itself in its pupa, and re-emerges as a butterfly.
There is life beyond death, and in that life, there's no body to kill.
So the horror is real, and awful, and done by God, but it's transient, a birth pain, really, for a spirit freed of the cocoon of flesh to enter into the afterlife. And that's not so terrible.
