Hi I'm going to talk about a weird xenoanthropology topic involving cannibalism and spiders now
I saw a pair of male and female wolf spiders in my bedroom today, within a few inches of each other. I took a picture, sent it to the group chat and made a joke about "aw they're on a date." I went back about fifteen minutes later, and noticed the only thing left was a leg (assumedly from the male being eaten post-copulation), and commented on this plus "I see the date went well"
Then I was like, huh. That is a very non-anthropocentric comment I just made (aside from the fact that I was labeling spiders mating as a date, which was pretty clearly anthropocentric). Seeing evidence of post-copulatory cannibalism and commenting on it as on par with human standards for mating rituals, and all that
Then I thought to myself, what would interacting with a sapient species that has similar practices work? Of course you have to do a certain amount of anthropomorphizing to play with this idea at all in a way understandable to a human, but I digress. Back to spider people
Like... how would that relate to social roles? Would it be acceptable to turn down post-copulatory cannibalism, or would it be seen as a cowardly or selfish thing? Would it be approached as an ancient practice from a time with fewer resources, which isn't participated in anymore as a sign that they have reliable resources?
Would there be cookbooks like 101 Best Ways To Cook Your Mate? What about some equivalent of last will and testimonies? How would a male think about the whole arrangement? What if a female didn't want to eat a male post-copulation? What if she only wanted to eat him a little bit? Would that be taboo, or considerate, or even kinky? How would legal things work? Would it be a private matter, or out in the open? Would it be seen as a romantic sacrifice, or a grief filled necessity?
Plenty of human societies have practiced cannibalism (almost always for ritual purposes associated with grieving or conflict) but what if there was a species comparable to humans that practiced it as part of a very vital piece of their life cycle? Upon the advent of producing sustenance outside of opportunistic hunting, how would a species adapt this part of their lives? You know??
