Agreed. The French Revolution is one of the top 5 historical revolutions when valued as a unitarian (Amount of Good) - (Amount of Bad). What most pro-revolution folk fail to mention is

* The amount of bad in a revolution is unpredictable and very large. You are fundamentally disrupting the institutions of law and order, which will embolden the worst in society and stroke a fear and self-preservation response in the population.

* Almost every revolution does not result in a high quality government taking power. The most common outcome is that the new government is worse than what it replaced, as the most violent and ambitious tend to thrive in revolutionary conditions.
