This whole issue turns out to be another Wiccan denial of the darkness inherent in nature, which I will discuss later. Harming and Hurting, these things exist in nature and we humans are part of nature. Thus, they are part of us. You harm plants and animals to eat them. You harm bacteria in the water you drink.
Life feeds on life.
The Traditional Craft is very family and Faith oriented, and if someone threatens the family, or the faith, then stopping that threat is first and foremost. If that means harming someone, that s what Traditional Witches will do, and there is no ethical injunction against it. The Craft, and the power it invokes, is not good or bad it is both. There is a time and a place for both. This is hard for New-agers to understand, but it is simply the way of things.
