Humans are desperately seeking an explanation as to why a 27-year-old German pilot "intentionally" crashed the plane he was co-piloting, killing the other 149 people on-board. I put the word 'intentionally' in quotes here because it really is very, very hard to make sense of what humans mean when they use that word in this context.
Evidence collected at apartment didn’t include suicide note or indication of motive
The Germanwings co-pilot who appeared to intentionally crash an airliner into a French mountainside, killing himself and 149 passengers and crew, received a note from a doctor excusing him from work but apparently tore it up, a German prosecutor said.
The prosecutor said evidence collected in a search of the apartment of Andreas Lubitz didn't include a suicide note and gave no indication of a political or religious motive for his apparent decision to crash the plane.
“However, documents were confiscated that contained medical information indicating an existing medical treatment,” the Düsseldorf prosecutor said in a statement.
Documents in the apartment showed Mr. Lubitz received a note from his doctor excusing him from work for a period covering the day of the incident, according to the statement. Other such notes were also found...
And so on.
The more perceptive among you may have noticed that Big Brains go haywire all the time, often with disastrous and tragic consequences for other humans or other animals. If you are looking for a "motive" in this or similar cases, you can stop that foolishness right now.
If you want to understand what happened in this case or countless millions just like it, then perhaps you might devote yourself to the study of the evolution of the human animal. Work backwards, from the crock of shit world you inhabit now to the beginnings of the hominin lineage some 5-7 million years ago. Along the way, for example, you will learn that those in the species Homo erectus likely had very thick skullcaps so they could better absorb crushing blows to the head from other males of their species.
And then you might further consider the profound mismatch between the bootstrapped crock of shit humans have created today and the paleolithic environment in which their Big Brains evolved. Or you might consider the under-appreciated but equally profound fact that evolution does not move inexorably toward perfection, as humans like to think, where the human species forms the perfect endpoint. During evolution's blind course, "mistakes" are made. But "mistakes" don't last long. Big brains going haywire is a case in point. Some people would say Homo sapiens itself is one of those "mistakes."
Or, you could take the usual route and call the co-pilot's action "God's Will," or say that "God moves in mysterious ways." Those are always very popular explanations when Big Brains go haywire.
Unfortunately, everything which goes on arises in the unconscious, which is the only place this particular instance of human craziness—co-pilot crashes airplane, killing himself and 149 innocent people—could have come from. Needless to say, humans do not accept this simple observation. Humans think their "conscious self" is running the show!
This fundamental delusion makes humans look for "motives" in cases like this. With regard to this alleged motive, there was no coherent Self called "Andreas Lubitz" who "intentionally" flew that jet into the ground for some specific political or religious reason which made sense to him or might make sense to somebody else. The search for some (rational?) "motive" is utterly pointless, and of course no "motive" will be found, as in all other cases where humans lose their always tenuous grip.
If you think the co-pilot was exercising his "free will" when he killed himself and those 149 other unfortunates, you can forget about it. The human terms 'intentional' and 'motive' are really beside the point when Big Brains go haywire.
That's not how the human world works, and the faster you learn that lesson, the better off you're going to be.
