Lions are predators (see photo below, or consult YouTube videos that provide intimate portraits of the predatory, violent behavior of lions).

Lions track down and stalk their prey. They catch their prey, and attack viciously and without remorse--with claws and teeth. They usually finish off the prey with a bite to the throat.

Lions do not "hate" the prey that they kill. They attack viciously and kill their prey in order to be able to eat their flesh. A lion's survival depends on devouring and digesting the flesh of the prey they kill. Lions have no concept of the prey that they attack and kill as an "enemy."

Human beings may attack and kill other human beings, rarely as individuals, often collectively. They do so when they define another group of human beings as evil enemies. The violent attacks they perform often are motivated or accompanied by hatred of the enemy--and the morally righteous belief that it is necessary to harm or destroy these enemies.

Human beings rarely consume the human beings that they violently kill. The enemy does not constitute food that enables the killer to survive.

The singular term VIOLENCE is often used to describe both animal killing and human killing. 

The conflation of the term VIOLENCE in this way lacks rigor. In fact, the two forms of violence are entirely different.
