I was just dividing the Grimm from the non-Grimm animals. The Grimm are part of the fauna of Remnant, but not the normal part of it's fauna. I never said the were "created" by death, nor that they multiply by killing. I said, that maybe, they multiply like the Darkspawn (without the Broodmothers), which is, not by killing, by injuring and more importantly, corrupting living beings, in this case, animals.

Wars are bad, because other than the obvious, they cause a great amount of negative emotions, which attracts Grimm. If the case is that bad, they could attract Adults, which are supposedly the ones that can cause real damage.
