what is so hard to understand with the concept of brainless? look, they were actually done repairing this wall hours ago, probably
they were just standing there inert, the only person you would feel bad about is your master for having to command them to repair the wall
but you don't, because he knows it was for a greater cause, this sacrifice was necessary
so you won't feel anything for these expendable cadaver of scavengers who dared enter a haunted crypt years ago, if anything, you should be suspicious of them, because any demon spirit haunting the place could hide inside of them
