Dark magic ??

Does anyone else believe in Dark Magic? My sister in law is crazy she showed me how she made her husbands always come to her and never get hard for another woman. Before doing that to her husband her best friend ended up pregnant by he same husband and she took a picture of her and did some crazy things and said some crazy things and the girl had a miscarriage. 
Do you believe in it?
