Psychologists say since years the western society is becoming more and more narcistic and sociopathic. The Medias are celebrating these characters, either they are pop stars or politicians. I read Lubitz was obsessed with flying, beeing a pilot. So he had no escape path for his career in mind if he looses his medical?
Perhaps the treating doctors failed to see this coming problem.
I know pilots who started further education during their career just not to be dependent on their medical, business administration or technical stuff for aviation management for example. They even don't need to change their company. I remember one SAR pilot who got trained as mechanic as he loved his unit so much. Just in case he was not fit to fly.
We all have resonable choices not to create a one way dead end road with our careers, especially pilots should think that way, beeing trained to see the wider picture.
