According to his friend Pandrea, Herseni was eventually sidelined by the National Legionary regime, after being denounced by lecturer Sorin Pavel—who had married Herseni's sister. In January 1941, the Guard and Antonescu went to war with each other, in what was termed the "Legionary Rebellion"; Antonescu emerged victorious. Herseni, now perceived as a "moderate" or "decent" Guardist, was able to escape the subsequent purge, and made his peace with the new military regime. Reportedly, he resumed his contacts with Ralea, assuring him that Sima, by then disgraced and in exile, had tried to curb his own party's violence. In May of that year, "Revista de Studii Sociologice și Muncitorești" hosted Herseni's homage piece to the economist Virgil Madgearu, who had been murdered by the Guard a year before. A year later, "Sociologie Românească" published Herseni's posthumous tribute to Andrei, referring to his "great stature" and "untimely death".
