"Even if she's not, and I'm pretty sure that she is," Hermione returned. "The Dursleys viciously mistreated my Harry as a child. I can't abide them to be alive in the world with that guilt on their heads, and Harry needs closure on his past if he is ever to forge himself a happy future. They deserve to die, even if I will do everything in my power to make sure that Lucy Dursley lives. She has no share in their culpability. The parents and cousin may be dead already for all I know, but I intend to finish the job if they are not."
