Why does it seem out of scope? In terms of biomass humans seem kind of insignificant. Some ants make slaves [1]. Some wasps torture cockroaches [2]. I don't know enough about them, but I imagine that bacteriophages would happily commit genocide [3].
I believe that humans are special because we're made in the image of God, but I mentioned the spiders et al because it felt like this whole thing was sliding into a philosophical realm where no one was defining their terms. Personally, I think if you're going to talk about morality and violence without indicating why you think humans are so important you should have a good reason why we aren't concerned about grass being oppressed because otherwise it's just opinions without consistency.
