Not sure about equal weighting to all possible options. Equal consideration, yes, along with, as you say a consideration of the evidence, which in turn would lead to recommendations to improve safety. In this case the principle cause was evident and subsequently admitted to. In the interest of a just culture the reason why there was no initial true statement of events should be discovered.
I am ex military (20+years) with a background of flight safety. I have flown the A330 and am aware of the topography of the control column and sidestick area and the forces involved.
There are some here on this forum who have blindly defended the pilot, others who you say want to lynch him. I would like justice to be done.
