Not to be too heavy, but I think this is important:

From "They Thought They Were Free," describing the German reaction to Hitler:

"Suddenly it all comes down, all at once. You see what you are, what you have done, or, more accurately, what you haven't done ( for that was all that was required of most of us: that we do nothing). You remember those early meetings of your department in the university when, if one had stood, others would have stood, perhaps, but no one stood. A small matter, a matter of hiring this man or that, and you hired this one rather than that. You remember everything now, and your heart breaks. Too late. You are compromised beyond repair.
