slytherin evil

In the car on the way to work this morning, I was listening to GoF - 
the first At Hogwarts chapter (and oh, how I LOVE Jim Dale's song!) - 
and was struck by one of the lines, in light of the recent discussion 
of Hagrid's comment in Book 1 that all the dark wizards came from 
Slytherin.
In GoF, Harry thinks to himself, as the first Slytherin is sorted, 
something like "Wonder if he knows that Slytherin has produced more 
dark witches and wizards than any other house..." which makes me 
think that yes, other houses produced dark witches & wizards and 
Harry knows it, despite what Hagrid said that day so many years 
before...
