None of that makes sense. If they're not alive and don't need to do those things then why do them? Why copy animals if they're no animals? Why become cautious and avoid destruction if they're not alive? Zombies have no soul and merely charge in to bit people. They care nothing of getting hurt and breaking down. Grimm want to live. They learn what doesn't work and try to stay alive. They want to accomplish what they see as their purpose or mission "to kill humans and survive encounters with human as they kill them". Whatever reason they beef with humans, I don't know. But if something wants to live, that means it must be alive in the first place. Only something with no self-preservation in teh least would willinging continue to harm itself despite pain or nigh destruction. Grimm don't act like zombies, they want to exist on. Because existing is living to them.
