Based on the information from Varmintguy's thread, the guy was bullied incessantly until driven to insanity. It can and does happen. Next to nothing is done about the bullying and never has been. Some people can get over it. Some never do. You keep pounding on people who already have problems and it wrecks them mentally. You end up with a person with a hate filled twisted mind planning on the most horrible way possible to inflict pain on other humanity in a raging suicidal burnout. Schools are extremely vulnerable targets.
