Quote from the Eulogy of William C. Patrick III, Expert on Germ Warfare and bioweaponeer for the U.S. Army during the Cold War:
"Mr. Patrick expressed no regrets about his arms work, saying he was comfortable with memories of killing animals and finding new ways to produce death. He said it was all part of doing his duty for his country in perilous times."
#Comment: I wonder if his personality-type was related at all to the likes of Shirō Ishii (a microbiologist and army medical officer who served as the director of Unit 731, a biological warfare unit of the Imperial Japanese Army) or Josef Mengele. Biological warfare seems to require and attract very special types of "doctors".
