Aside from the similarly fated Russian invasions, they are completely different. Napoleon was not genocidal and contrary to his popular reputation was not a warmonger. England & the coalition was generally the aggressor because they wanted to restore the Monarchy (The Bourbons) to France & weren't happy about the Rights of Man and Liberalism that the Grande Army was spreading.

Was Napoleon the aggressor in his invasion of Russia?

[rkk3]

Yes. The backstory... England was very hostile to France, especially because of Pitt, and France lost its navy at Traflager so Napoleon's only option was to get all of Europe to Embargo England [1]. Russia eventually decided to trade with England anyway which is what triggered the French invasion to enforce the embargo. The other factor is that after Napoleon divorced Josephine, he had the option of marrying the daughter of the Emperor of Austria or Russia, he choose Austria which cooled relations with Russia.
