After Bellatrix had Cruccio’d her a few times she was left on the floor to twitch and bleed to death, Bellatrix had got what she wanted from Griphook and it didn’t matter anymore. "Mudblood’ is who she would always be, still dripping from her wound. Malfoy had been the first person who called her that word, he wanted to make sure early on she knew she did not belong in his world, she wasn’t sure why that memory made her cry in that moment even after being tortured and mutilated by a psychopathic witch. Maybe that was why, she knew Draco was a child and he still had hurt her more, she always knew Bellatrix was evil, Draco just wanted everyone to believe he was.
