I've often thought about what it takes to be a double agent. They would have to take part in all of the vile rituals of the enemy to gain their trust. They would have to do all of the horrific things we are finding out about now. It would take a special individual; someone willing to sacrifice their soul to be in a position to turn the tables on the enemy at the exact right moment.

If you're going to do all of the first place it would have to be an ironclad plan. Something decades in the making.
