I’m still not sure what the “evil” is in a turtle egg being eaten before it hatches. The embryo isn’t conscious, so it’s not like a sentient being is dying. How is that more “evil” than, say, an abortion or the death of a slime mold?
Edit: It just occurred to me that this might apply to most lethal negative mutations, which are for the most part lethal before birth, correct? I might be very wrong about this.
