Is Consentual Cap Cannibalism Immoral?

i did an interview with michael sandel at harvard, and we ended up spending the bulk of the interview trying to understand each other's positions on the question of consentual cap cannibalism. And i kept saying, you know, well, look, it's if they consented, and if i had reason to believe that this wasn't going to have a ripple effect of terrible consequences on society. Maybe respect for life in general would go down if we allowed constential canibalism, i don't know. But if we strip away those potential concerns, then i don't think it's immoral.
