Perhaps heroic. Perhaps anti-heroic. Beethoven for example, dedicated and un-dedicated the Eroica symphony to his hero/then anti-hero.
Perhaps heroic to Jews: Napoleon “restored” the Sanhedrin; more importantly he freed the Jews from the Ghetto literally tearing down the physical Ghetto gates in several Italian cities; he also extended civil rights to many Jewish populations in France, Italy, and Eastern Europe.
Perhaps anti-heroic: he became a boogie man for Jews in Eastern Europe – his name frightened little children for at least a century after he died.
Needless to say, conflicting views of Napoleon are not limited to a Jewish perspective.
