At age 15, Beto O’Rourke wrote a short story fantasizing about killing children, mass murder
"This feeling pervaded everything in my life, yet the first few months after realizing my goal, I had done nothing. Then one day, as I was driving home from work, I noticed two children crossing the street. They were happy, happy to be free from their troubles. I knew, however, that this happiness and sense of freedom were much too overwhelming for them. This happiness was mine by right. I had earned it in my dreams. As I neared the young ones, I put all my weight on my right foot, keeping the accelerator pedal on the floor until I heard the crashing of the two children on the hood, and then the sharp cry of pain from one of the two. I was so fascinated for a moment, that when after I had stopped my vehicle, I just sat in a daze, sweet visions filling my head. …
The more people I killed, the longer my dreams were. I soon quit my job, and stayed at my house in an almost comatose state".
