Perhaps. But then why is it when so many women end up killed or severely hurt by an ex-spouse the guy was obviously a psychopath but she still stayed for "reasons," or evidently never saw it coming? Rihanna and Chris Brown. Nicole and OJ. Scott and Laci Peterson.

I doubt Sodini had murdrerer vibes 24/7, much less up through the time when he decided on his "exit plan." To me he comes off as someone who was anti-social with deep-seated psychological issues who finally blew a gasket.
