What is the impact of black magic on people?

Blackmagic is real, and dangerous. People get hurt when you use black magic on them. If you are a beginner then you must not know the Wicca 3 Fold Law. It's kind of like karma for the horrible magic you put upon the person only it is 3 times worse than what you did to the person. And yes, the karma can be maiming or death. I advise you not to use any black magic ever.
