This made me think about this interview with a guy that came close to shooting up a school. The things some kids get put through in life. It makes me grateful for the people who raised me, flawed as they were.
I think these shooters are made by their environment, their families, their schools, their federal handlers. The intense, violent, neverending, and demoralizing psyop and advertisement we call a society. They are driven or allowed to drive themselves to suicide and the most effective way they can think of to express and share their rage is to take others with them. But, I've written similar in dozens of threads and comment sections all around the internet and will probably continue to do so for the rest of my life.
