Aide-de-camp - Napoleon was everything but warmonger... he actually never started a war by himself, but always marched into war after it was declared on France or on their allies by others... Napoleon initiated peace talks several times, he tried to make British to accept peace several times, but after Trafalgar, British just didn't listened anymore, as they saw themselves secure..
Napoleon's tactics was never about threatening major cities, but to engage and destroy standing armies - once those are dealt with he always made peace with defeated nation. With Russia in 1812, he didnt wanted to defeat Russian badly, as he wanted to make them his Allies.. that was the major misconception on his side,because at that point, Russian Csar was no longer impressed by Napoleon,but due to some dream, he saw himself as a protector of the Europe against Napoleon...
While Napoleon being an Emperor, he wasn't like other European rulers, he was much more "liberal" - French could occupy any post no matter what their origin was, there was saying - each French soldier carries Marshal stick in his bag.. French even today still use some parts of his Laws in their Law system.. Practically, Europe by defeating Napoleon in 1815, just postponed inevitable, and was to face the same thing again in 1848... one could even say, that by defeating Napoleon Europe lost 30 years of social and national development, but its probably far fetched, and even his defeat played crucial role in further development in some states - simple soldiers from Austria and Russia were stationed in France for some time, and witnessed the new political system. Once they got back they demanded some changes home, which started movements that in the end made Absolutist monarchies to fall down later..

even though i would not blame just him for all those dead during those times - European Absolutist FEUDAL monarchs tended to wage wars before, and would wage it against somebody else if Napoleon was not there... To me it looks strange, that modern people find Napoleon as some kind of a monster, while they completely ignore his opposition placed on European thrones, that suppressed their populace and denied them their base rights..
