Animals Aren't Savage. Humans Are.
Tigers don't kill needlessly. They kill to eat.
Humans don't eat each other. Not anymore anyway. It's quite a rare occurrence in modern society.
But we kill each other. In large numbers at times. Definitely more than most if any animal group would kill their own.
We kill on emotion, difference of ideals, out of a sense of duty and sometimes because someone tells you to.
The fact remains that for majority of the times, it's not about "survival".
Yet, when someone acts in a savage way we may call them an "animal". Or maybe even refer to animals as being savages when they are merely trying to survive using what they have.
By all aspects, humans are savage. It's rather an insult to associate "savagery" with animals.
Look within for problems. Savagery starts with the individual.
