Agreed. The grimm are unambigous monsters. This is a world where the soul is a quantifible thing, and the grimm don't have it. Nothing in any of the behavours of the grimm we've seen so far show that they are only agressive for the reasons the animals are, never have we seen any back down for a fight or fight defensively. They see a human they attack and they keep attacking until either human or they are dead.
