The show makes no sense. It is a lazy attempt at giving a backstory to a character who more or less serves as a model of senseless cruelty. It's a horrible jumble of bright colors and a lot of staring (seriously, people in this show don't blink, it's bizarre).
The show only seems to serve as an excuse for Hollywood to further demonize the mentally ill in media and ruin what was already a great story (One Flew Over The Cuckoo's Nest).
