Grimm do not equal wild animals. Wild animals hurt humans because they need food, they're territorial, or the humans hurt them first and they react to it because we need food.

Grimm hurt humans because they can. They don't need the territory; they have plenty of it where the humans aren't settled, since humanity is stuck in four concentrated locations. They don't need food, because they don't eat. Humans only attack them if they attack humans, which is what each Grimm battle has been. If anything, humans are the wild animal being oppressed by the Grimm.
