"Yeah. But they weren't evil, murderous toadies for Voldemort, at least. So I can sleep at night knowing that." Or he could have. Harry tended to dream too much to really sleep well. Old nightmares and new ones all mixing up in his head frequently enough that he was never an easy sleeper.
He hated Draco making fun of his parents. Harry didn't really get how someone could be enough of a wanker that they could poke fun at murder. But then, he hadn't been raised by people who thought that was all part of the evil henchmen job, so it wasn't something he could understand, probably.
