The crew are innocent until proven otherwise. Everything said so far is speculation even if some facts may point to crew involvement.
JAL123 is a good example where pilots kept the a/c in the air for 32 mins after the vertical stabilizer disintegrated which was never matched by anyone on a simulator.
Japan Airlines Flight 123 - Wikipedia, the free encyclopedia
"Elapsed time from the bulkhead explosion to the final crash was estimated at 32 minutes – long enough for some passengers to write farewells to their families.Subsequent simulator re-enactments (of the mechanical failures suffered by Flight 123) failed to produce a better solution, or outcome; despite best efforts, none of the four flight crews in the simulations kept the plane aloft for as long as the 32 minutes achieved by the actual crew."
