Animals that do follow the non-aggression principle should have their
life respected. The ones that do not, obviously have made their
decision.
Nojus, I know you are a smart guy but this thesis falls apart really quickly under scrutiny. Just think about the application of what you're talking about here. It might 'feel good' but it does not function. I'm not sure why you would assume animals are moral agents to begin with.
If you want to show an example of how this theory would work I'm sure it would lead to greater understanding.
If you claim the moral right to kill anyone who hunts or traps wild animals in unclaimed territory, I await your crusade into the lands of indigenous people around the world.
If you want to protect animals set up a nature preserve, OK?
PS. If readers are confused there are previous threads where this is discussed in greater detail.
