This reminds me of the Carnage one-shots written by Warren Ellis back in the 90s, "Mind Bomb" and "It's a Wonderful Life." In both of those one-shots, we got some disturbing insights into Carnage's POV of the world around him. You've followed that line quite well, though the most chilling part is that you never tell any part of the story from Kasady's point of view, but only through Ashley Kafka's eyes, which makes his mind games even scarier, in a way. Because we don't know what he's actually thinking, planning, or feeling, but whatever he's up, he's the one winning and he's winning by undermining the bastions of society that we depend on to keep believing we are civilized and good and honest --- everything inmates in asylums for the criminally insane or prisons for the plain old criminal aren't. But as Kasady challenges Kafka here (and we the readers by extension), how do we know we aren't the same as them deep down, other than our own convictions and the comparative luxury and comfort we are used to?
