Their is a wide misconception of "Black Magic" & "White Magic". The energy or the source used from one to the next is the same. It is much like the energy of your house it can be used to power your lights or an electric chair.
It's intent for the outcome is programmed by the one casting the magic and that is what determines black or white aspect of the magick. Intent is the operation that dictates how the outcome or magick will manifest
Personally I find "Black" magick,
Normally but is not limited to. Intention with forethought, to injure - mentally, physically, emotionally, or spiritually or an act that deprives another of their "free will".
Although their is some talk of the 3 fold law I have not found this to be true but rather find in my own workings that magic is nether good nor bad and you make the call on what it is for you. Many times you may do things which inadvertently or due to a lack of deliberation cause others harm just as with anything else in life. We all experience trials and difficulties, most of which we bring upon ourselves. It's just part of life, and is part of our evolution.
And I completely agree with what Whiterav3n said.
