Forty-eight-year-old George Sodini was a deeply frustrated, bitter man. Yesterday, his anger, resentment and rage finally exploded into the premeditated madness of violence. Sodini strolled into an all female aerobics class at LA Fitness in Pittsburgh, PA, shot three young women to death, wounded nine, and then committed suicide. What was Sodini so angry about? It appears, based on his own self-published blog entries beginning more than nine months ago, that Mr. Sodini was frustrated primarily about his difficulties with women. He complains of an inability to find a girlfriend since he was twenty-three, not having sex for almost two decades and, most recently, failure to find a date during the past twelve months.Could chronic sexual frustration have caused this catastrophe? To conclude so would be a gross oversimplification of this and other violent offenders' profound existential embitterment, fury and frustration.
