Well, that's an interesting question, isn't it, with regard to JKR's 
magic.  If witchcraft is not good or evil, what is meant by the Dark 
Arts?  Why are the Unforgiveable Curses unforgiveable?

It's fairly obvious, IMO, that much magic can be regarded as morally 
neutral, but capable of being pressed into the service of either 
good or evil just like, say, high explosive, but *some* magic seems 
somehow to be intrinsically evil - though as yet we have seen 
remarkably little in the way of examples.  We haven't had much 
evidence of magic that's intrinsically 'good', either.

Thoughts?
