It does seem concerning that there appears to be sociopathy occurring in soooo many ppl! It's like this young man thought he was deserving of his parents' assets and their lives were not of any value other than the assets they could provide him. I think for some reason ppl are viewing others as "less human" and "of lesser value" than themselves, sort of "objectifying" others.
I also just saw a report that disruptive, rude behavior on airplanes is greatly increasing.
