The Villain Leage's Resurrection Policy and Laws

The Villain League has a policy that says no member can stay dead forever. Whenever the need arises to have a certain member in a villain's conquest crisis, Mirage will drag that villain's soul from the underworld, order Facilier to stab the ghost's heart area, fill it with darkness, and thereby bringing it to life. Basically, all villains are stuck having to serve the forces of darkness and never be free in death.
