You walk into a celebrated high class restaurant, and at the bottom of the menu, it reads “Human meat steak. $10,000”. You ask the waiter who fetches the chef. The chef comes out and explains that after decades honing his craft, he feels like he’s a master of his craft, and now he’d love the honour of cooking a steak taken from his own body. If anyone purchases the steak, a skilled surgeon will remove half a pound of meat safely from the chef, who will then prepare it for you, and the chef is visibly keen to serve this.
As a vegetarian, I honestly don’t feel that this would bother me, if I had money to spend, the only reason I wouldn’t go for it is that I’d worry the chef would come to regret giving up chunk of his ass or leg or whatever, and I’d be partially to blame, or that the chef was not thinking straight otherwise.
