Jean-Paul Marat
Charlotte Corday held Jean-Paul Marat responsible, as is laid out in great detail by Stanley Loomis, but for Madame Roland, it was Georges Danton. Danton was also accused by the French historians Adolphe Thiers, Alphonse de Lamartine, Jules Michelet, Louis Blanc and Edgar Quinet for appearing to have done nothing to stop them.
