I suggest that the truth is more important than silly little ego entries to this forum.
I am pretty sure the majority responses of concern here are more about safety than ego. The current non-punitive system that rules the most trusted countries' aviation sectors is what works - it is proven through statistical analysis and applied knowledge of human nature to foster the growth of safety culture.
I agree there is a need to know exactly what happened, Mtoro. That is the purpose of the AAIB investigation. Criminal proceedings, may, in their investigative process discover "a cause", but are far from conducive towards preventing future occurrences.
