I hadn't mean "plot" hole. I meant that it would just lead to taking one step to deactivate the face either way. But they just need Crawford to activate the Faces, which i guess has already happened since the Faces have popped out. Destroying his corpse or killing Keith shouldn't cause deactivation, since they were able to kill Crawford after the first face was activated. So killing Keith or getting rid of the corpse shouldn't have any effect.
