Scroll down to verbs. When you’re talking about someone else, there’s an implication of unfairness. This is why vegans don’t eat animals or use animal products. If the animals could consent, there would be nothing wrong with it.
I reiterate: it would not be unfair for Astarion or Lenore to drain several pints of blood from my neck

And exploitation, when talking about living things, implies unfairness and nonconsent
