Couple of things:
Andreas had a girlfriend at the time of crash
Andreas had a girlfriend in 2014
Andreas a ladies man?
The girlfriend from 2014 said that he was not sick but was a nut
Now it is revealed by the 2014 girlfriend that Andreas has been planning the crash into the mountain for over one year.
"When I heard about the crash, I remembered a sentence, over and over again, that he said," the woman, a flight attendant of 26 named only as Maria W., told Bild. "'One day I'll do something that will change the system, and then everyone will know my name and remember it'." "I didn't know what he meant by that at the time, but now it's obvious," she said. "He did it because he realised that, due to his health problems, his big dream of working at Lufthansa, of a having job as a pilot, and as a pilot on long-distance flights, was nearly impossible." "He never talked much about his illness, only that he was in psychiatric treatment."

Question - how long has Andreas been planning the attack before he decided to tell his girlfriend Maria W? If he told his girlfriend in 2014 you can best be sure that Andreas has been planning the attack for well over one year.
What kind of man plans an attack on innocent souls for years? A Jihadist!
Or one possessed by demons...
