• The Zohar (II, 36a) identifies Manasseh as the anti-Hezekiah — a king who systematically reversed every spiritual defense his father had erected, reopening every channel to the Sitra Achra that Hezekiah had sealed. The rebuilding of the high places, the erection of Baal altars, the Asherah placed inside the Temple — each act was a deliberate re-installation of the klipot that had been cleared. The Zohar describes this as the most thorough spiritual sabotage in Israel's history, because it was performed by one who knew exactly which defenses to dismantle.
• The placement of the Asherah idol in the Temple is described in Zohar (III, 282a) as the violation of the Holy of Holies' sanctity — the feminine aspect of the Sitra Achra installed where the Shekhinah's feminine holiness was supposed to dwell. This was not merely idolatry but a direct replacement: the impure feminine displacing the holy feminine, transforming the Temple from a beacon of divine presence into a broadcasting station for the Other Side. The Zohar calls this "the abomination of desolation" and connects it to Daniel's later prophecy.
• Manasseh's practice of necromancy, divination, and consulting with familiar spirits is discussed in Zohar (I, 208a) as the opening of portals to the deepest klipot — the realms of the dead where the Sitra Achra stores the trapped souls it has captured. A king who commands a state necromancy apparatus gives the Other Side governmental authority, creating a regime that operates with demonic intelligence. The 613 mitzvot explicitly prohibit these practices because they constitute formal alliance with the enemy.
• The shedding of innocent blood "till he had filled Jerusalem from one end to another" is described in Zohar Chadash (Eichah, 92a) as the creation of a blood-field — a territory so saturated with unjust death that the Sitra Achra achieves permanent territorial control. The Zohar teaches that innocent blood cries from the ground (as Abel's did) and when the cries accumulate beyond a certain threshold, the land itself vomits out its inhabitants. Manasseh's murders created the spiritual conditions for the Babylonian exile more surely than any political factor.
• Amon's brief, wicked reign and assassination is discussed in Zohar (II, 37a) as the final proof that Manasseh's contamination had become generational — the spiritual poison transmitted from father to son, the Sitra Achra establishing a self-perpetuating cycle within the royal house itself. The Zohar notes that the "people of the land" who killed Amon's assassins and installed Josiah were the hidden Tzaddikim — the remnant who had survived Manasseh's persecution and now acted to preserve the Davidic line for one final reformation.
• Sanhedrin 103b records that Manasseh is one of the four kings who have no portion in the world to come (though the Talmud also records his repentance). Manasseh's fifty-five year reign is the longest in Judah's history and its most comprehensively demonic: he rebuilds every high place Hezekiah demolished, sets up Baal altars, makes Asherah poles, worships the host of heaven, builds altars in the Temple courts, passes children through fire, practices witchcraft and divination, and sets up a carved image of Asherah in the Temple itself — the complete Sitra Achra takeover of the covenant infrastructure.
• Avodah Zarah 36b records that the carved image in the Temple was the single act for which the Shechinah permanently departed from the First Temple. Manasseh's idol in the holy place fulfills the "abomination of desolation" in its original historical iteration. The second-heaven entity behind Manasseh achieves what the Sitra Achra has sought since Solomon's apostasy: installation in the Temple itself.
• Sanhedrin 102a records that Manasseh manipulated the prophecies of Moses to support his idolatry. The Talmudic critique of Manasseh as Torah-manipulator — using his extraordinary intelligence and learning to rationalize the demonic — is the supreme cautionary tale: the most educated tzaddik who abandons the 613 mitzvot-as-armor becomes the most dangerous instrument of the Sitra Achra.
• Berakhot 61b records that those who die as martyrs for Torah are elevated to the highest levels. Manasseh's filling of Jerusalem with innocent blood — the prophets sawn in two, the tradition identifying Isaiah among them — is the second-heaven purge of the tzaddik-warrior class. The Sitra Achra, when it holds the throne, executes its primary targets: the prophets who can expose it.
• Gittin 57b records that those killed by wicked kings are among the martyrs. Amon's short reign and assassination demonstrate that even among the demonic, internal conflict prevents stability. The Sitra Achra's human avatars ultimately turn on each other — the demonic does not reward loyalty, only utility.
