Angra Mainyu, in Zoroastrianism, represents the destructive and malevolent force that opposes Ahura Mazda, the supreme god. This dualistic belief system portrays Angra Mainyu as the origin of disorder, death, and moral decay, in contrast to Spenta Mainyu, the life-giving force. Scholars such as Maneckji Nusservanji Dhalla highlight his role as a wicked opponent, describing his ineffective efforts to challenge Zarathustra and his eventual downfall at the hands of Ahura Mazda’s power.
Elizabeth A. Reed emphasizes the religious duality, presenting Angra Mainyu as the opposite of light, truth, and virtue. Texts like the Avesta portray him as a source of anguish and suffering, yet his ultimate defeat under Ahura Mazda’s rule remains a key element of Zoroastrian end times, symbolizing the ongoing battle between harmony and disintegration.
