"Yes," Justin said without a moment's hesitation. He stopped to meet Dennis' gaze with a hard stare. "I must live every day with the knowledge that my sister died because I am a wizard. But it doesn't change who I am. And all the revenge in the world won't change who you are. And ridding the world of purebloods would do absolutely nothing to ease your pain. It would be a disgrace to Colin's memory. He would hate to hear you talk like this." He knew that was probably a step too far, but if Dennis wasn't going to listen to reason, maybe he needed to be shocked into it.
