The predator lifestyle is risky. A predator cannot afford even minor injuries. Non-human predators attack the weak, the immature, the old. Never an adult, capable of fighting back. A cow with a broken leg can still eat grass. A lion with a broken leg will starve. This defines the level of violence a predator will exercise. It will choose the easier prey. It will not fight another predator except to survive or reproduce. It will use bluff and noise to intimidate, yet will flee from a real fight.
