I don't know if OP is the author, but if so could you suggest some papers where people actually go about implementing ethics into a system even just as a very basic PoC? I'd be really interested. I've looked for papers but even in a survey completed as recently as 2018 it suggested the closest thing we have is a graph database sitting on top of the Moral Machine (which is a survey of ethical questions).
