What is your evidence against it? Clearly you know very little about the matter as all of this is well established and any biologist or TV wildlife program can set you straight. Few predators "finish off" their prey though they may often kill it during the hunt, once the prey animal is disabled they start to feed. House cats, for instance, will capture, release and recapture the prey animal, sometimes for hours. Wolves and Dogs will hunt and not feed, often leaving the prey animal to die from it's wounds. Also look into how predators teach their young to hunt. It is very unpleasant. I'm not saying that factory farming should be allowed. In fact, I think future generations will correctly judge us harshly for the unnecessary atrocity that is modern agriculture.
