For this reason, many witches tend to stick to positive spells: spells that are cast that do no harm, but only aid the subject of the spell. My informant noted that even if the subject of the sorcery is someone one dislikes, the witch ought to cast a positive spell. For example, say you go on a date with someone, and you find out that they are very possessive. You just want them out of your life. You would cast a spell that brings to their attention something ``good'' to get their minds off of you. Maybe, the person gets a promotion which forces them to leave the city, or neighbourhood conversely leaving you alone.
Although this is the main rule of conduct, it is at times broken by those witches who perform black magick. Carol knew no one, personally, who practised black magick; however, there was reference to a popular media witch who wrote several books on black magick, and his travails. Notwithstanding, there is no Devil in the Wiccan religion. The stigmatism of Devil worship arose from the popular Christian Church - in attempts to coerce the pagan population.
