Here's a theory. Grimm simply regenerate after being killed. No idea how long it takes, but it haoppens. One condition for immortality, depending on the method, is to relinquish one's soul or be souless in the first place. Mybe Grimm manifest because they are concentrations of dark emotions that are opposite to the soul. And they keep coming back every time.
