They are scared because the Chantry teaches them to be scared. Because they don't understand. Andraste's teachings that magic should serve mankind, not rule over it didn't mean we should imprison them and keep them as Templar slaves. A blade can kill anyone as well as a fireball, and yet we don't go around cutting the hands off of children so they can never wield one, do we?
