Well... the Hindu name for evil is "Mara" if that helps... there are demons and such within Hinduism, but none of them are given the... importance (?)... that the devil is given within Judeo-Christianity, God is all powerful, so any foe (e.g., Mahishasura) is annihilated immediately by God or one of God's devotees (e.g., Mother Durga) and subsequently either: a) reincarnated, or b) liberated by God's mercy... the "devil" isn't really a problem for Hindus
