There is no place or counterpart for it in Witchcraft. Most Witches do agree that we are responsible for our own lives. Witches do not now, and have never had, a Satan figure in our religion. He is a Christian concept, and they have the right to him. In the pantheistic religion of Witchcraft the belief in a totally evil figure or being is excluded, because anything that exists contains the devine God and Goddess energy.
Witches hold a deep reverence for nature and animals.
They too are part of the God and Goddess, therefore a Witch would not use any animal as a sacrafice in any ritual. There is no need to try and steal power from another being. Witches are secure in their inner strength and the power that comes from this harmony balance and peace. Some Witches are vegetarians, and some Witches are not. Those that do consume meat try to maintain a respectful attitude for the animal who's life was taken, and often times offer energy to aid in its passing.
