First Counsel to Emperor? Why not, I'm only surprised he didn't go on to having himself declared a God. After all Caligula made it.

No self doubt, ambition, a tremendous ego and also a willingness to gamble everything on continual throws of the dice. From refusing assignments he didn't like as a young officer, to the "Whiff of Grapshot" in the Paris streets, to making his own treaty with the Austrians, to the debacle and desertion of his Army in Eygpt; Napoleon's acts had gotten others beheaded/shot. He gambled high, putting his life on the line in exchange for the next giant leap forward. Later when the imagined (or real?) star was sinking, he had not learned to cut his losses and gamble less wildly and for smaller pots.

He never learned when to hold or to fold em, as the American bard K. Rodgers once sang.
