Yes it is unfortunately possible and in this case very likely. I wouldn't say that the pilot was deranged. Obviously, other factors contributed to the psychological state and wellbeing of the FO.
Pilots are just as likely as anyone else to suffer from psychological and mental health issues. The profession places many challenges on your home life, and relationships. You can add many other factors (fatigue, financial) and it's all cumulative.
I was leaning towards crime, terrorism and possibly pilot intervention, especially when reports circulated about the Captain not being allowed access to the Flight Deck.
Depressurization did not seem plausible. There is absolutely no reason for depressurization incapacitating the Flight Crew.
There have been 3 confirmed suicide flights and 1 unconfirmed suicide flight in recent years - Silk Air, FedEx, GermanWings, and MH370 (unconfirmed).
I hope people can keep things in perspective. Pilots are monitored closely through medical checks and Human Factors, and Cabin Resource Management Training which is done yearly. Of course this depends on the jurisdiction. In this case, the German JAA jurisdiction is one of the most stringent in the world. People need to be calm and not over-react and help instigate more procedures which might introduce a new set of risks or problems.
GoldenWings is owned by Lufthansa.
