"That's a big question," she admitted, slowly stroking Teddy's fine hair that was currently brown since he had been upset. "You might need to ask Remus more about it. From what I know is that he's... unique. He might be the lone werewolf bitten as a child raised as a wizard. Almost all children die if they're attacked... in fact he might be the only one. But some are wizards that were bit. The problem is they end up registered and life for a registered werewolf is awful. Their wands get taken away - can you believe it? Then they have... virtually nothing. They end up with Greyback because they have little choice. Would someplace to go help? Maybe if it was no where, they could somehow keep the wolves from ranging too far. Maybe."
