Magick is neutral, it can't be "Βlack" or "White". You can consider "Black" and "White" as the polar opposites of magick. Using the white pole you attract things to you and using the black pole you push things away from you. Both are very useful, depending on the situation you have to deal with. It would be useful to mention that baneful magick is always the work of the black pole, and this can give some bad connotation. Apart from that, the idea that white magicκ is good and black magicκ is bad comes mainly from Holywood. You can think magick as a tool. You can use it to make something useful and beautiful or to make a trap to harm someone. The tool can't be good or bad, but your intention can be. Thus, the term "White Magick" describes the intention to help yourself and others (with their consent) and "Black Magick" the intention to harm or manipulate others. OR your intention to help others without their consent, because you violate their freedom of choice. This is also true when you think you are doing good for them. You do not have the right to interfere in their lives and their choices. Using magick to harm or manipulate others is unethical and attracts bad consequences to those who do it. Wiccans take it very seriously and forbid their members to do so, otherwise, they can no longer be called Wiccans.
