duwde, you do not have to be a pilot to understand human error. All of the aspects that you and others believe to be unthinkable can and will, in the right circumstances, happen.
The circumstances are driven by the situation; the runway, the aircraft, the crew, and many, many external factors.
No one should blame the crew, and even after a considered investigation with an awareness of hindsight bias, the best outcome for safety would be to identify the contributing factors; - those issues which convinced the crew to do …, not to do …, to believe, to remember / forget.
These are the aspects of every day life; the difference in being a pilot is that anyone of those factors could be the difference between a normal day and life.
