Not sure what the fascination is with killing children. Sure, it's kinda lame they are 'invincible', but it seems more like a problem for the children than death. Exploitation anyone? "That's right, little Jimmy, just walk through that long hall of pressure plates, onto that pit of fire, and grab that piece of armor for me. Oh, and watch out for the hordes of dead that will come alive to curse you for eternity for disturbing their rest. THANKS!"
