Magic blooms only in rare souls.“Do you really intend to turn your back on your own kind? It was you who said we could reshape the world!When we allow ourselves to be consumed with anger, the only victim is ourself.I was never your enemy. Then or now.With or without you - I'll burn down their world.The disapproval of cowards is praise to the brave.Kill me, then, Voldemort, I welcome death! But my death will not bring you what you seek... there is so much you do not understand...Kicked out of Hogwarts for endangering human life with a beast. Yet one of your teachers argued strongly against your expulsion. I wonder, what makes Albus Dumbledore so fond of you, Mr. Scamander?Grindelwald: "We want only freedom. Freedom to be ourselves."
Vinda Rosier: "To annihilate non-wizards."
Grindelwald: "Not all of them. Not all. We're not merciless. The beast of burden will always be necessary."To survive so long with this inside you, Credence, is a miracle. You are a miracle. Come with me!Our war with the Muggles begins today!I wish you were working with me now towards a world where we wizards are free to live openly, and to love freely."Kill me, then!" demanded the old man. "You will not win, you cannot win! That wand will never, ever be yours -" And Voldemort's fury broke: A burst of green light filled the prison room and the frail old body was lifted from its hard bed and then fell back, lifeless.The frail man sat up, great sunken eyes fixed upon him, upon Voldemort, and then he smiled. Most of his teeth were gone... "So, you have come. I thought you would... one day. But your journey was pointless. I never had it."A law that has us scuttling like rats in the gutter! A law that demands that we conceal our true nature! A law that directs those under its dominion to cower in fear lest we risk discovery! I ask you, Madam President - I ask all of you - who does this law protect? Us? Or Them? I refuse to bow down any longer!You came today because of a craving and a knowledge that the old ways serve us no longer... you come today because you crave something new, something different. It is said that I hate Les Non-Magiques. The Muggles. The No-Maj. The Can't-Spells. I do not hate them. I do not. For I do not fight out of hatred. I say the Muggles are not lesser, but other. Not worthless, but of other value. Not disposable, but of a different disposition. Magic blooms only in rare souls. It is granted to those who live for higher things. Oh, and what a world we could make, for all of humanity. We who live for freedom, for truth and for love.We've lived in the shadows for too long.Grindelwald: "Who represents the greatest threat to our cause?"
Krall: "Albus Dumbledore."
Grindelwald: "If I asked you now to go to the school where he is hiding and kill him for me, would you do it for me, Krall? Credence is the only entity alive who can kill him."Quotes about Gellert Grindelwald
Grindelwald doesn't seem to understand the nature of the things he considers simple.Grindelwald. You cannot imagine how his ideas caught me, Harry, inflamed me. Muggles forced into subservience. We wizards triumphant. Grindelwald and I, the glorious young leaders of the revolution. Oh, I had a few scruples. I assuaged my conscience with empty words. It would all be for the greater good, and any harm done would be repaid a hundredfold in benefits for wizards. Did I know, in my heart of hearts, what Gellert Grindelwald was? I think I did, but I closed my eyes.This is his symbol, I recognised it at vunce: Grindelvald carved it into a vall at Durmstrang ven he vos a pupil there. Some idiots copied it onto their books and clothes thinking to shock, make themselves impressive . until those of us who had lost family members to Grindelvald taught them better.
