According to Hagrid, "there's not a single witch or wizard who went bad who wasn't in" what house?

Hagrid believes that almost all Dark wizards have their origins in Slytherin House. While it is true that many of the worst wizards come from Slytherin, there are numerous examples from other houses. Additionally, many Slytherins are good and can even be kind, with large numbers of the House's members fighting against Voldemort in the Second Wizarding War.
