"Oh no, Tommy. Remember how I gave oath I would use no Unforgivables on you? I won’t Imperius you, so you will be fully in your right mind to experience your last minutes. I won’t hit you with the Cruciatus Curse, simply because Cruciatus-Curse victims don’t bleed. I want you to die by bleeding out—exsanguination, Hermione calls it—screaming all the while. And the Killing Curse? Not for you, Tommy. I’ve witnessed two people die by Killing Curse—for them, death was quick and painless. Your death shall be neither quick nor painless, Tommy."
