There's a thin line between an experimental treatment with some potential merit being trialed on vulnerable people, and a mad scientist just trying things "to see what will happen."
A lot of terminal people have, historically, had pretty terrible things done to them on the guise of "well they were going to die anyway!"
I for one welcome medical and academic oversight of experimental treatments. Terminal people are especially in need of protection as they will grasp to any hope no matter how slim or misguided.
