Napoleon's actions in fact delayed revolutionary ideas from gaining influence in the rest of Europe, making it take until 1848 until anything noteworthy happened again, because who could talk in favor of the Revolutionary ideas when talking positively of these ideas was, by propaganda from the nobility and the likes, the same as talking positive of the massmurderer Napoleon?

I can't say I agree with you there. After Waterloo the United Kingdom of the Netherlands was formed as a dam against the revolutionary ideas still very much alive in France. It seems that heads of state of England, Prussia, ... still felt threathened by those revolutionary ideas.

And it didn't take until 1848 until anything noteworthy happened. The southern part of the United Kingdom of the Netherlands revolted in 1830 and founded Belgium in 1831 with the most liberal constitution since then. A constitution which is still in use to this day I might add.
