Animals in general cannot reason at a high enough level to avoid instinctual behavior.
> if we apply human moral standards to the animal kingdom
Which we should not, since human moral standards are for humans. Animals can at best behave in a way that suits us.
Or in summary, since we can be nicer, we should. Animals can't, so making excuses for human evil saying "animals are more violent" is a non starter IMHO (no one is making excuses for humans here , AFAIK).
Of course we can define violence in a way that does not include morals, which would make my argument "defending animals" void. But my (probably not the most benign) interpretation was that the definition of violence used was one that included some sort of morality, as if animals could do better.
Very interesting convo, thanks.
