That's a fair point, but then you're getting into the question of whether a kill only counts if it's observable from the perspective of the killer. I'm leaning towards "no" simply because the dude squished a ball of eggs all rolled up together and wouldn't be able to count them one by one after having done the deed, so it doesn't make sense that would be a requirement.
Maybe grasshopper eggs have souls but prokaryotic organisms don't?
