According to Isaac Luria (1534–72) and other commentators on the Zohar, righteous Gentiles do not have this demonic aspect and are in many ways similar to Jewish souls. A number of prominent Kabbalists, e.g., Pinchas Eliyahu of Vilna, the author of "Sefer ha-Brit", held that only some marginal elements in the humanity represent these demonic forces. On the other hand, the souls of Jewish heretics have much more satanic energy than the worst of idol worshippers; this view is popular in some Hasidic circles, especially Satmar Hasidim.
