Every human relates to nonhuman animals, only the most people do it in speciesist ways; they see nonhumans as a means to an end. A specific of speciesism is that as a nonhuman you may be seen as “regular” food. I.e. eating you doesn’t count as a form of cannibalism. The mental divide that human societies draw here is that you may be a generally physically usable source to the degrees where you may be “destroyed” under the utmost imaginable forms of torture and pain.
