If you're not careful when torturing enemies, you'll wind up with hordes of  the little undead whiners overloading your Temple. (If this happens, you may consider refining your torture chamber skills, so you can convert them rather then kill them.)

Your best bet is to train them as high a possible, and then use them as disposable troops when you clash with the enemy. They'll take the initial brunt of the attack while your more valuable ranged fighters the enemy from a distance.

Ghosts do have some helpful traits, however. Their spirit status gives them the ability to pass through locked doors and to see invisible creatures. While only occasionally useful, this is enough to make you consider keeping at least one posted in a strategic position.
