You forgot Peter Singer in your list of bioethicists.
I have no room left on the list so have to be very choosy. I kicked John Wayne Gacy off to make room for Eric Pianka and his plans to annihilate 90% of the human race. Now that is serious bioethicking. Peter Singer never made the list in the first place. He's a sissy. He's nothing but wind. Kill defective babies, he says, but does he lead the way? Has he strangled even one baby? No.
Dr. Ronald Cranford is on the bubble. The only thing that keeps him on the list is that he's marginally less creepy-crawly than Jack Kevorkian.
