Per what @Brad and @Larry Kart said, the legacy is simultaneously more nuanced and more ugly than merely going along. The Vichy gov't had its own policy priorities and had some leeway to defy and/or supplement German initiatives when it wished to do so. They (or at least many of them) viewed murdering of Jews as a feature, not a bug, of Nazi domination - hence much of the subsequent revulsion and shame.
Also, the early Furst books *are* highly recommended if you like high quality fiction.
