"No, Ronald, you don't understand. Voldemort wants to live forever and be in charge. I've shown him how to do both and not have to constantly fight wars. Dumbledore did terrible things to manipulate people. He erased Snape's memory of making up with Lily Potter before they went into hiding. She wanted there to be no regrets in his life. But that didn't suit Dumbledore's plans, so he erased it. He had obedience charms on Remus to make him take bigger risks with the werewolf packs. He made Shaklebolt and Tonks do things that could have gotten them fired or arrested. He would have sacrificed all of us to have things end his way. My being a muggleborn does not invalidate my way of thinking or mean my opinions on things don't matter. I understand better than you do. I wasn't taught to worship him my entire life and overlook the evil he did or caused."
