Personaly, I'm with the Blucher and the Prussians. It would have been better if he'd been stood against a wall in 1814 and shot. It would have saved a lot of lives.
You can't deny his contribution to the law and constitution of Europe, but from 1812 on he appears to have lost sight of reality. Having broken his word in 1815, he was lucky not to have been hung!
He was also involved in some very murky deaths. By modern standards, his regard for International law would put him on a par with Hitler, without 'the Final Solution'. However Napoleon's legacy has been far more longstanding and probably beneficial. But it was still a 'high price' to pay, both for France and the rest of Europe.
Not for nothing did mothers frighten their children with the words, 'Behave or Boney will get you!'
