Generally No. Witchcraft is generally used for what can be seen as positive causes - e.g. healing, helping, protection, trying to see a possible future, or seeing the present/past in a new way. It can draw upon many beliefs - including ancient gods and goddesses from cultures like the Greeks, Celts and egyptians and those which are based upon elements, nature and space - and can have allot of variation within it. Like all people you can have those whose motives and actions are questionable, but often witches and followers of Wicca/Witchcraft follow the belief that "what you send out returns 3 fold" - i.e. work done for good, like healing, will bring good/healing for you times 3. This equally applies to work done for 'bad' and so sending out harm will harm you 3 times more. Furthermore, a good and common practice within witchcraft is to ask permission of the people involved, or if this isn't possible for some reason add in the intention that "And it harm none, so mote it be" - i.e. let the spell/etc only work if it doesn't harm anyone. You then have the influence of perspective - what one person may see as good is bad in another's eyes, However generally the last mentioned intention/phrase sorts this out. Sadly, some forms of witchcraft have gained a bad name. This could be partly put down to the amount of propergander put out by those either afraid of the unexplainable magic or or by those under the misconception that it is purely bad. Interestingly enough, the government of Mongolia is still trying to remove local Shamanism - which has recently been shown to work thanks to the BBC's book and program (which should come out soon) called 'The Horse Boy' - and the only remaining branch of the Spanish Inquisition is in Peru, where local Shamanism has also continued. When you then take into account the amount of negative media towards magic, the general belief that the old ways of healing and helping are either bad or fictional is quite understandable. The other contributing factor is probably the fact that those who have done magic for what is seen as a negative cause has probably been noticed far more then the subtle but strong positive influences caused by magic. You then often have the influence of religion. Witchcraft is more a set of beliefs, practices and ways of life then a religion. It also tends to vary allot according to different practitioners and their views, and as there is no single book formalising what must and must not be done, it is very flexible and adaptive, which is probably why it has survived so long. You also have some religions that have continued the medieval concept that all forms of witchcraft are bad. Sadly, as they are formalised and strong beliefs they have a strong influence over the general view.
