Maybe, but I think the idea of them surviving off of negative emotions makes more sense then just killing. Predators such as sharks, for instance, are specifically built to track down the scent of a wounded creature from as far as a mile away from their current location. As a result, many sharks can converge on a single wounded animal quickly, similar to how the Grimm congregate in larger and larger numbers as the negative energy of their prey rises indicating a potential need for sustenance in their biology. I also wonder why the Grimm wouldn't kill animals that also possess Aura, and are a threat to their livelihood since animals do have some degree of sentience, not akin to human or Faunus, but still developed. I also think it wouldn't make sense in a situation such as a city where a small group of Grimm, or even a single Grimm, break in and are surrounded by thousands of people at once. If the soul poisoning theory is true then these type of Grimm attacks would end rather quickly for these Grimm since they'd be greatly weakened. Moreover, why have teams of four Huntsmen/Huntresses to deal with the Grimm if you could just send out an army? Strength in numbers plus the mere presence of so many people would overwhelm, or at least weaken lesser numbers of Grimm to the point that killing them is made much easier. True, much of what I noted is just speculation at this point, but I find the negative emotions theory to be more plausible then others.
