One senses that all the Bolsheviks, even those who ended up as cold-blooded autocrats, had been on a journey from idealism to something else, and didn't notice - to mix periods - when the Rubicon was crossed.
A lot of my idealism was frustrated by the end of the '60s because of the way things went with the assassinations and the sense that the political establishment was so fixed in its ways you couldn't change anything.
