He was impregnably armoured by his good intentions and his ignorance...
Pyle had been silent a long while, and I had nothing more to say. Indeed I had said too much already. He looked white and beaten and ready to faint, and I thought, 'What's the good? he'll always be innocent, you can't blame the innocent, they are always guiltless. All you can do is control them or eliminate them. Innocence is a kind of insanity.'
He comes blundering in and people have to die for his mistakes.
That about says it, doesn't it? This administration is 'innocent' in the worst sense: naive, overidealistic, careless, blundering and, most of all, ignorant.
