Is it fair to say “it is wrong to kill”?

# EDIT: I wish I could reply to everyone but there is just a lot of comments coming in - I appreciate your thoughts, please carry on this discussion on your own time. I haven’t been replying to many comments here lately but I really appreciate you all. This will likely be the last time I post here as I don’t think I have any more to add to this topic! <br><br>It recently occurred to me that the conviction that it is wrong to kill is absolute, yet it is not absolute in the real world, neither is it absolute in people’s minds. It is not wrong to kill animals. It is not wrong to kill plants. It isn’t wrong to kill in self defence. A lot of people (particularly Americans) believe that it is not wrong to kill somebody who is attempting to illegally enter your property. <br><br>When we really break it down there is a large list of things that we are allowed to kill. Does it make sense to then just say that “it is wrong to kill”? Is that accurately describing a feeling that we really have? <br><br>Let’s go even further and look at some more abstract examples - all living things in the ecosystem must kill for survival. We even consume and kill parts of ourselves in an autophagy process. <br><br>Is “it is wrong to kill” just a hollow phrase?
