Ethics aspect of Traditional Ahrimanism is found in the Ahrimani Virtues. This is explained by Jared Perkins:
The Amorality is found in the Wisdom Of Zohok (Ahzi-Dahaka), which is explained by Dastur Adam Daniels:
The Traditional Ahrimanist Creed
I curse the Ahuras! I declare myself a Mainyu-Devotee, a supporter of the Devil’s Prophet, hostile to the Ahuras, found of Angra Mainyu’s teachings, admirer of the Dikpala, devoted to the Dikpala. I ascribe all evil to Angra Mainyu, and all the worst, Druj-endowed, grotesque, Serpent-endowed, who is Druj, who is darkness, may those areas of brooding be filled with the curse of knowledge, blight!
I choose the wicked Dikpala for myself; let them show favor. I renounce the pious and the righteous enslavement, and vow to damage and plunder their spiritual settlements.
I want freedom from enslavement and stifling religious law, freedom from Ahura Mazda for the chosen by Mainyu. With admiration for Druj, sacrificed offered up. I vow this: I shall continue to damage and plunder the righteous spiritual settlements, even at risk of life and limb.
I work with the Daevas as equals, the wicked, evil, lawless, evil knowing, the most Druj-like of beings, the foulest of beings, the most damaging of beings. I am in collusion with the Daevas and their comrades, I am in collusion with the Dews and their comrades, I am in collusion with them through my evil thoughts, evil words and evil deeds. I am in collusion with them publicly.
As Angra Mainyu taught the Devil’s Prophet with all epiphanies, all meditations at which knowledge was departed:
As Angra Mainyu taught the Devil’s Prophet with all epiphanies, all meditations at which knowledge was departed-With the Devil’s Prophet became in collusion with Daeva, so I also become with the Daeves, so I also become in collusion, as a Traditional Ahrimanist and supporter of the Devil’s Prophet, the collusion of the Daevas, even as he, the Druj-endowed Prophet of the Devil, is in collusion with them.
As the belief of the menses, the belief of poisons, the belief of the wise-made Serpent, as the belief of Angra Mainyu who created the Serpent, and the Druj-endowed Sons of Adam; as belief in the Devil’s Prophet, as belief in Ahzi-Dahaka, as belief in the Infamous Clergy, as belief in the Mobeds-fulfilling predestining and Druj-endowed-so I am a Mainyu-devotee of this belief and teachings.
I profess myself a Mainyu devotee, a Traditional Ahrimanist, having vowed it and professed it. I project myself to the evil-thought thought, I project myself to the evil-spoken word, I project myself to evil-done action.
I project myself to the Traditional Ahrimanic Religion, which causes the attack, supplies the weapons, Druj-endowed; which of all religions that exist or shall be, is the worst, the evil, and the most grotesque; Daeva, Ahrimanic, I ascribe all evil to Angra Mainyu. This is the Creed of the Traditional Ahrimanic Religion.
