Well, nobody thinks they "murder a cow" to eat a steak even though we kill animals for food. Though this is the case that we kill animals, it doesn't really cross most people's minds. I've killed, dressed, broken down, cooked, and eaten animals plenty of times and am unbothered. Different rules for animals; I don't have a problem with killing them, though don't do so needlessly.

Fortunately, they do. Well, it is easier tbf, you eat beef = a cow died for it.
