Tuc is right when he says the gross negligence occured in the higher-level corridors of MoD and, after the event, negligence became wilful obsfuscation.
Of course, no-one knows for sure whether the catalogue of failures in rushing into service an aircraft with so many known faults had a bearing on the crash as there was so little of it left to investigate. Even the AAIB said evidence was sparse.
We would do well to remember that
"no evidence of failure" does not mean "evidence of no failure". That introduces doubt - mountains of it.
As to the assertion of Wratten + Day of 'too low, too fast, in poor weather' is nonsense. As others have said, no-one knows what they could see from the cockpit. What the lighthouse keepers saw or didn't is irrelevent. It is what the crew could see that matters - before or after WP change. As no-one knows this, with any certainty, the verdict of the ROs is a gross injustice.
If the crew had flown wilfully into culmo-granite then yes, it would be suicidal and murderous. But for that reason, I don't believe anyone would have flown wilfully into the very obvious mass of the Mull. So that leaves the only logical explanations as:
1. Total loss of Situational Awareness - but the WP change belies this. Even if it were, this very human failing would not merit the label of 'gross negligence'.
or
2. Heads-down distraction by something major (even then I don't believe the crewman between the seats would have let them, such was his reputation).
or
3. For some reason (there are many possibilities), the aircraft wouldn't let them turn left. For example, don't forget that the inconceivable amount of left rudder (when the ac was turning/yawing slightly right) has never been satisfactorally explained - possibly because of the impact, possibly not). Additionally, such a phenomenon had recently occured with the ac, as had numerous false warnings.
Doubt, doubt, everywhere doubt.
But high-level negligence and incompetence 9 months before the crash......provable and certain. What do you think a judge will decide is relevant?
