Aren't we missing the point again?
As much as the explained story has an emotional value, it is not what this is all about. It is about people with mental problems using aviation as the "escape". It's about people who are a part of society who end up in a moment where they want to step out of that society for whatever reason. When those people happen to be pilots, it can be a problem for aviation.
If you feel the story is a problem of aviation, you should talk more to people around you. It is by far a unique story related to aviation.
