"No matter what, as far as I'm concerned, whether a wizard used a Levitation Charm, raw magic, or even a Muggle bulldozer to kill an enemy, it was far better than using Avada Kedavra. The reason was simple: in an emergency, a normal person could use a Levitation Charm to kill a Death Eater, but no matter how desperate they were, a normal person could never cast Avada Kedavra without any reservations!"
