Oh, make no mistake. Lev would die in a violent and horrible fashion. Technically he doesn't heal from wounds, it's just Na'lsa weaving and holding his flesh in place. If he were to leave, every single injury Lev's ever had since becoming possessed would happen at once. It very nearly happened waaaay back when with a certain grenade. Na'lsa isn't above sacrificing him if he thinks it will 'forward the greater good' though. But you're right. He's dug in so deep that he probably can't leave.
