I say that gets pretty loose with the meaning of words, and ends the same place.
It boils down to this: organism doesn't like to be hurt, pained, killed. Why? I don't know. That's how organisms behave. That's what humans verbalize. Perhaps it's an atavistic genetic trait that serves no other purpose but to preserve the species, for whatever reason. But that's how it is. It's selfish to the bone.
