I don't think I particular fear death. Fear of death is a monkey brain thing. I don't want to die because I enjoy living. But if I had the choice between dying immediately or living for a few more minutes while being pushed through a meat grinder, I think I, and everyone alive, would choose to die immediately. It's not too difficult to imagine torture and pain so horrific that even monkey brain prefers death.

Human brain can make that judgment wherever it wants. I think the general case that shitty medical routes are just not worth it is often true.
