UR is a novella where the lead character is introduced as someone who has become verbally demeaning. While he sometimes has internal dialogue where conversations are repeated, and he has some writings that portray ideas for work and are about characters that are missing something or are somehow wounded, his projection of these characters while depicting a different and warped perception of reality had not ruined this perception until a new device that he purchases changes his grasp of reality.
He has become demeaning and the isolation that ensues and during which he uses the new device leads him to get a worse sense of what is real and to lose his grip of what is alright to do.
Stephen King portrays this Wesley character who is a professor. Wesley is mean verbally then progresses to lose his sense of reality and eventually hurts someone badly. The police reaction is fantasy based and weak. Then, the novella ends with a denial that something bad has happened and with a failure to get Wesley legally accounted for his actions; this adds to the horror.
In the moment of the crime Wesley is self-entitled, grandiose, and not feeling for the victim while in a distorted reality. Horridly the character that is narrated as the lead has been criminal.
