Well, when I was doing the Russian Revolution I talked about any parts of the new regime that compromised the ideas that sparked revolution in the first place in AoS1.
When you start the French Revolution, for example, you'll learn about the idea of equality, liberty and fraternity. Quite clearly, however, all these ideals were left unfulfilled as the CPS and Robespierre's dominance during the Terror persecuted anyone who could be labelled as counter-revolutionary. Compare the camaraderie during the Tennis Court Oath (20th June 1789), where the lone person who didn't agree to the oath was respected, to later on when the Revolution has progressed to a degree of radicalism where whole towns (for example, Lyons) were demolished/destroyed/burnt down just for disagreeing with the Civil Constitution of the Clergy.
In the Russian Revolution, obviously the Bolsheviks took over with a pure Marxism-Leninism agenda in mind. Lenin has always had the goal of a world-wide revolution, and Russia was only a stepping stone to that. But circumstances, such as the war, famine etc etc forced him to compromise on that ideal, as well as give up on war communism to introduce the NEP which reintroduced elements of a capitalist society, thereby a step backwards away from the ideal communist utopia.
tl;dr:
You're basically playing a balancing act in which you discuss how the revolutionary leaders held up the ideals that began the revolution and how they had to compromise because creating a new society was just too hard.
