Schaeffer and Koop on Experimenting on Humans

Schaeffer and Koop said

[O]nce the uniqueness of people as created by God is removed and mankind is viewed as only one of the gene patterns which came forth on the earth by chance--there is no reason not to treat people as things to be experimented on and to make over the whole humanity according to the decisions of a relatively few people.
