From a huge animal lover and a believer that my dogs are better than 50% of humanity...
Sophistry.
There is no morality in the wild.. There is survival of the fittest in the wild..
They behave in a fashion that promotes survival of their genetics. In herd animals, the sick, the old, the injured will be pushed to the outside of the herd so they are eaten first.
In family groups, as in wolves and lions..It is routine for challenges to pack leader to result in death (fairly human) but that is followed by the slaughter of the young of the former leader so the females can come into heat again.
Your definition of morals and ethics defy anything that I recognize.
Not arguing religion here..Just biology.
