You have your facts wrong. There are no wars or acts of oppression among animals. Sometimes there is localized and short-time conflict (over food or territory). But there is nothing like revenge or hatred.
Also no faith, love, hope…
These are all not functions of language (though we can verbalize them), but of reason.
Language is a tool. Yes, you can go out growing pumpkins with your rake and hoe, but someone can still come along and decide that they want your pumpkins and they’ll take your hoe and whack you upside the head with it. No words are necessary. Stopping language will not stop hate and violence, it will just stop the ability to verbalize it.
It’s usually when people run out of arguments that they resort to violence…
Tools are not in and of themselves evil. What we do (with or without them) can be.
How does one communicate one’s basic needs – like hunger – without words? If one is able to do so, then another would be also able to refuse on the grounds that there is no food to give. And do so even if there is food – thus, lying. And then hungry person finds out there really was food, and gets angry, and attacks the person who denied them. Revenge and violence.
Sin is inherent in fallen humans. Taking away language does not take away one whit our propensity for it. It does take away (or at least severely inhibit) our ability to learn of Jesus’ sacrifice and how to avoid sin.
So what is better – to eschew words and language, or to stop using language for evil and start using it for what it was originally intended for: to glorify God?
As I said above, I’m no philosopher, never studied it, don’t know all the big words and theories and don’t sit in the tubs often. So I could be completely wrong.
