I Became Karen Overnight

Karen is a nurse who loves her residents so much that she is willing to make a deal with the devil in order that they could be saved from the horror of having their souls ripped from their bodies. The question that remains is what was Karen's deal and what would her fate be as the devil had no intention of sticking to the deal. Karen had to call on the very beings in heaven she did not think existed to help her save the world from being destroyed.
