Of course they would all be horrified, even Adams who, of course, couldn’t imagine the destructive force of limiting individual freedom. The French Revolution wasn’t horrible at that point. It followed the same path that our Revolution did. We were very lucky to have the right people, culture and fortune to succeed. The French weren’t as fortunate...ditto the Russian Revolution a century later. Jefferson and Madison of course erred, but at least they worked to retain the original vision of individual freedom.
What revolution, save the American revolution, ended up being for the better? I can’t think of any.
