I personally do not take a side for white or black magick. The white and black concept comes majorly from the concept of white being good (Innocence, purity) and black being bad, or dark (Death, curses). I believe magick is neither "good" nor "evil" but both. I personally cannot choose a side because magick is dangerous as it is. Color wise, I solely practice White magick because I am a good witch. I do not believe in the bad magick, as in I don't believe anybody should practice it, unless their matron God/Goddess requires it then by all means follow their word and wisdom.
Blessed be and much love and light
