Actually, no. 'They made me do it' was also not the resonse I gave. Napoleon took the same chances the privates took, was wounded twice (in contrast, Massena never was, but that means nothing really), and had 19 horses shot out from under him.
Napoleon would have accomplished nothing staying after the Berezina. He did accomplish rescuing, for lack of a better term, the situation in central Germany by settling things in Paris and getting a new army in the field. Many of the survivors were also sent back to France to cadre new units and many of the commanders were sent back to organize their units. The wreck of the Grande Armee was abandoned by Murat, but I would argue that it wasn't by Napoleon. He also had to balance his responsibilities as army commander and head of state. There were bigger fish to fry.
I could see the criticism if he left to go back to have a great time while the remnants were suffering. I would recommend Lejeune's memoirs as well as Boulart's to see what these two stalwarts said of the situation.
It should also be remembered, and seldom is, that the Russians lost at least 250,000 (plus an unknown number of irrgulars and Cossacks) and they were also at the end of their tether. The likelihood of another battle was just about nil.
Finally, Napoleon's escort had orders not to let him be taken alive by the Russians. Just a minor point.
