If your question is "was the Terror awful?", I'm sure you'll have a near totality of french people agreeing with you. If you ask "in retrospect, was the Terror awful enough so that the French nation would have been better off without its Revolution?", then I don't think you'll get many agreement.
The deaths associated with the Terror were plentiful, that's true, but this period was also carefully framed by the bourgeois class who took power afterwards. In terms of deaths, it's around 40k people. The american civil war was 700k deaths. Before Trumpism, would any american say out loud that abolishing slavery wasn't worth it?
The thing is people don't care about how many rich people there are out there, as long as they can get a good life out of their labor (good job, good house, etc) but since capitalism has optimized these out of the reach for most people nowadays, then they start to blame rich people for everything, with the definition of the word 'rich' here being very fluid, ending up to mean just about everyone who has more than they do, and not just your Bezos, Musk and Saudi kings, so any taxes on the "rich" ends up only on the hard working middle class again.
