The predator may have no consciousness of being cruel but is cruel just the same. American Indians and other cultures who tortured their enemies to death might not have though it justice instead of cruelty, but cruel it was just the same.Of course it does
A predator that kills its prey is not cruel. Animals act on instinct and as such cannot be cruel because those behaviors are hard wired into their behavior and the animal has no choice but to act that way. You are anthropomorphizing nature by attaching adjectives like cruel to what is behavior that is in accordance with the nature of the animal or of the natural world itself.
The abortion issue is far more complicated. The legal and ethical question there is if a fetus has all the rights of personhood that we as a society recognize in all born persons. And if you think that at the instant of conception is when all rights or personhood should be granted to the unborn then you are stepping into a mire where it has to be decided what rights of the unborn are put before the rights of the woman and when.
If you want the fetus to have all rights of personhood at the instant of conception then the first thing to be decided is how you want the government to be notified of the existence of this new person that just happens to be unborn at the moment. After all if the government doesn't know a person exists then there can be no protection of that person.
Should the government make it a law that the results of all positive pregnancy tests be reported along with the mother's name address SSN etc? What about the fathers name address and SSN? Should doctors have to supply this data to the government without permission of the mother? What about home pregnancy tests?
And that's just the first hurdle in the fetal rights of personhood argument.
And in my opinion, anyone who equates the law and rights as being the consideration in abortion and cruelty to the unborn child is not part of that is engaging in some serious cognitive dissonance.
