Many folks here at WS have suggested that Casey is a sociopath, and that's fine. I doubt there is anyone here who is qualified to "diagnose" Ms. Anthony, including myself. That said, I grew up with a Borderline sister and recognize many of the same characteristics in Casey. Borderlines see everything in black or white - there is no grey. They either love or hate anyone and everyone with whom they come in contact and can change colors at the drop of a hat.
One day, someone can be the Borderline's BFF while the next day, Casey wants to throttle that individual. Everyone tiptoes around the Borderline on eggshells because one never knows what "color" the Borderline sees. Family members live in fear of what the Borderline's next move will be - calling the police, threats of suicide, running away, etc. The "game" never ends because the Borderline always finds a way to get his/her ducks in a row, says "Jump!", and everyone asks, "How high?"
George and Cindy (and Lee) are no different from any other parents/siblings who have lived with a Borderline: They have lived in constant fear of Casey and have learned during the course of this trial that they may very well have been her next targets. jmo
