What began as all things made new in 1790, had turned into a challenge to the established system of the world by 91, picking a fight and polarizing the nation, with us or against us by 92, into blame throwing, faction fighting and the terrible search for revolutionary purity by 93, into the backstabbing of 94.
Robespierre had done in so many of his former comrades that the ones who were left had to get him before he got them, simple as that. There is a definite trajectory there, he was not only not a moderate, he was not capable of moderation- very much less so than Napoleon even- and he was always going to keep pushing until he was stopped.
What we got @ very largely was a Robespierrean France, which ran out the limits of its' possibility space and was brought down by how fratricidally self- destructive it was.
What it needed to survive and persist a little longer at least was less emphasis on revolutionary principles over the value of human life, and much less willingness to cut fellow travellers' heads off over fine points of political detail. Good luck getting any of that.
