An idle philosophical point after reading one too many spy stories: When a part of the government that does confidential work takes some basically good people, isolates them and their children from society, and has a rather profound effect on their minds and spirits, the only opprobrium involved falls on the government agency, not the people involved. If you decide to build the unhappiness house, the souls inside will be unhappy.
Hence my present aversion to the cult of Le Carre, though I was once a devoted reader (and prayed the office for the dead, sitting in the old apartment by the transcontinental rail in Fargo, when I head that he had passed away). Popular perceptions about confidential government work changed after those BBC mini-series, and it's rather important for a democracy to have the correct idea about the nature of its government agencies. Don't idolize the shock troops, as someone said once.
No opprobrium on the souls involved. Absolvo omnes. But do try to mend the agencies.
