Not sure this is the best example becauss there is a similar issue there of phones being made via basically slavery, I hypocritically say typing on my Samsung phone (though looking into buying a fairphone next which is the best I can possibly do while still having the practical neccesity of a smartphone)

The difference there is though that I would have no moral problem with building the phone and writing the software, physically capable or not. I'm not saying people should need to physically be able to kill the animal all by themselves, just that they should be morally able to, if given a gun pointed at an animal's head, pull the trigger and be ok with that decision

My point is not to be the gatekeeper of what's right and wrong, my point is to force people to make those decisions themselves and to be morally consistent. If people are ok with killing animals then that's fine by me, the bit I don't like is the level of abstraction we have that means people don't have to think about the consequences of their choices too deeply
