Luke Ford writes: I just watched this documentary about Medal of Honor winner Desmond Doss, a Seventh-Day Adventist hero from my childhood. And I felt split. My heart warmed to his story but my head said that if more people were pacifists like Doss, the world would be worse. Judaism holds pacifism to be immoral. You may not stand by while the blood of your neighbor is shed (and much of the time, the only way you can prevent this bloodshed is by killing the aggressors).
