Darvand
In Zoroastrianism, darvand, in its original Avestan form dregvant means 'wicked'. It is an ethical appellation of unrighteous persons. Angra Mainyu, the Evil Spirit, is a dregvant or darvand or wicked, as Spenta Mainyu, the Good Spirit, is ashavan or righteous. "Thou Ahura Mazda, most recognize only two classes among mankind, the 'ashavan' or righteous and the 'dregvant,' 'darvand' or wicked to whatever religion they may belong. Those alone among Zoroastrians, who think good thoughts, speak good words and do good deeds are 'ashavan' or righteous in thy sight.
