Pfft! Some lurker, you have 2 posts, which clearly makes you a and not yet a .
About the actual article, that is indeed tragic. It's sad that anyone would consider taking their own life over something as replaceable as a suburban house.
I wouldn't worry about yourself yet, as the early cases of aggression I've read about appear to be driven by foreclosed owners belief that if they owned a house once, and did not want to give it up, then it should still be theirs. It takes a large moral leap to go from "I'm going to destroy this McMansion before the bank takes it back" to "I don't have as big of a house as I would like so I'm going to injure that guy living in a 1400 sq ft house built in the 70s."
My gut (and the gut has more nerve endings than the brain - maybe) tells me that the average person has to descend towards destitution before they start acting out on another person just minding their own business. Take this guy, if he loses the house, he apparently hurts himself. But if he's having trouble getting food to eat, well who knows.
