Jessica:

I just had to respond to this post because I've been wondering the 
same thing.  I've always taken his statement to mean that every witch 
or wizard who went bad came from Slytherin, not every Slytherin is 
bad.  I refuse to believe that every single person in that house is 
evil (they may not be nice, but that's another story), and I don't 
believe that JKR would make such a broad generalization in a book 
that continuously reinforces that you should not just take people at 
face value.  There's a quote to back me up too: the description of 
Slytherin in CoS on page 77 US Ed.

the house that has turned out more dark witches and wizards than any 
other

It just says more, not all.  I still have to look through the other 
books for more.  Does anyone else know of any quotes to support this?
