Who Told You to Be a Mage in an Apocalypse Game?

Harry Potter: Magic Awakened arrives as a game world, only to become a doomsday survival game? As The Chosen One, I don't see what's wrong with being able to cast Avada Kedavra. As a wizard, isn't it perfectly normal to stop using Avada Kedavra on people and start using it on zombies instead? What, you say I belong in Azkaban? How dare you insult The Chosen One!
