Answer 2

Black magic is regarded as dangerous and potent in all religious beliefs[citation needed] . Christianity is a prominent example of this, which of course entails a history of segregation, purging and witch hunts. In the Christian faith, black magic is regarded as the work of The Devil, and the agents of darkness[citation needed] . Eve is the believed reason for magic entering the world, as Sammael the fallen opened her eyes to the secrets of existence, and thus forbidden magical secrets entered the world[citation needed] , hence why women have been widely subject to prejudice throughout History[citation needed] . In the Pagan faith, magic is considered only as good or as evil as the intent for which it is cast[citation needed] . Black magic is a heresy in Paganism, as even using it in vengeance against an enemy is considered un-pagan and an exploitation of the powers we possess. When Goddess' or God's powers are invoked for harmful practices, this is considered an offence against them, and the promulgation into darkness. Women here are honoured in this particular faith and for these practices, unlike in Christianity. Magic is encouraged to better one's or those around that person's life.
