Acho que poderiam ser usadas sim! Parece que eles estudaram bem a arte de matar, ou da eutanasia (como preferir) e os efeitos de diferentes substâncias letais, de certa forma...um importante legado! Mas, grande parte das experiências eram sem propósito e sem comprometimento científico, sendo a maioria dos resultados irrelevantes!
Achei um artigo bem interessante sobre o assunto:

"Euthanasia had already imposed itself in Germany during the third decade of the century
with the elimination of
mentally disturbed people, disabled and terminal patients. The “Child Extermination Program” of the Reichausschuss at Berlin-Wittenau, the “T4 Action” of Bunke and Eicke and the elimination of disabled children by professor Heinze must be recalled.
At Brandenburg-Gorden hospital the first gas chamber for children was at work, a dress rehearsal for Auschwitz, and doctor Hefte, called “doctor death”, killed children, subjecting them to painful pneumoencephalographies for experimental purposes. These are examples of an activity well documented in a review article published some years ago [10]. Euthanasia was applied to Jewish people becoming terminal in the camps after suffering the horrors of Nazi detention. The murder of these Jews as lebensunwerte Leben (lives not worthy to be lived), even though life was made unbearable by the Nazis themselves, was still a medical act of mercy, as was the murder of Muselmänner, or men turned into living skeletons by the Nazis.
The participation of many Nazi doctors in the notorious “selections” at Auschwitz, in murder by morphine and barbiturates and then by phenol and finally through gassing with the sadly famous Zyklon B, which was simply cyanide, of hundreds of thousands of people can only be understood through the fanatical conviction on the part of the Nazis that after all they were simply practising medical acts according to the concept of “Gleichschaltung”, or coordination, dominant at the time. The experimentation in vivo on men and women and the cruel and slow killing of children had the same rational basis. Scientific experiments were being carried out, Nazism championed scientific research and many Nazi doctors belonged to German universities where they made careers for themselves. After all, experiments were carried out on individuals who were eventually destined to gas chambers because guilty of being Jewish and of polluting the Nordic race."
