Medical schools under the thrall of social justice have revised the H.O. according to a version written in 1964 by (no kidding) a guy named Louis Lasagna that includes this gem:

"If it is given me to save a life, all thanks. But it may also be within my power to take a life; this awesome responsibility must be faced with great humbleness and awareness of my own frailty. Above all, I must not play at God."

I suppose it's the abortion/euthanasia loophole.
