How come Malfoy got away?

Which Malfoy? Narcissa, Lucius, Draco, all of them? WEll, since Narcissa Betrayed The dark lord, the whole family would of been shunned, and Voldy would of killed them. But since he died (:'O)
They were spared his fury. Now, your probably thinking Wouldn't they be in Azkaban? NOPE since Narcissa saved Potter, they were also spared. If u ask me, They are obviously stocked up on Felix Felicis
