VATICAN, Feb 27 (LSN) – Bishop Elio Sgreccia, the vice-president of the Pontifical Academy for Life, reinforced the pope's condemnation of prenatal screening and killing of embryos,  in an address to the Academy Thursday. He noted that the diagnostic tests were characteristic of the eugenics movement which culminated in the Nazi era.  In Hitler's time, however,  scientists were unable to identify “undesirable” babies before birth.  Modern technology has allowed doctors “to select embryos, and proceed like Hitler.”
