“Kill me then,' panted Harry, who felt no fear at all, but only rage and contempt. 'Kill me like you killed him, you coward-'DON'T-' screamed Snape, and his face was suddenly demented, inhuman, as though he was in as much pain as the yelping, howling dog stuck in the house behind them- 'CALL ME A COWARD!”
“I know you are here to kill me. Shoot, coward, you are only going to kill a man.”
“And when the creature spoke, it used Harry’s mouth, so that in his agony he felt his jaw move...“Kill me now Dumbledore...”Blinded and dying, every part of him screaming for release, Harry felt the creature use him again...“If death is nothing, Dumbledore, kill the boy...”
“Killed?" said Hagrid loudly, staring down at Harry. "Snape killed? What're yeh on abou', Harry?""Dumbledore," said Harry. "Snape killed... Dumbledore.”
“And you're the biggest coward," I hissed, then caught my breath in my throat as his blade cut deeper."Don't call me a coward," Tobias said, "I'm not!""Have you come here to kill me?" I asked. "Because I'll scream when you do and it'll wake up the princess and probably a whole lot of other people and you'll get into trouble.""You'll be dead.""Yes, but you'll be in trouble.”
“I'm too much of a coward to kill myself. And too much of a coward to live”
