Lookleft; looking at outcomes and learning for a minute. If as you suggest Dj has an "attitude' problem then CASA and the ATSB are still failures at generating a useful outcome from this mess because they fail to label the problem as behavioural.
Furthermore their treatment of the event has created a saint when as you say, we should all be learning the lessons about where "attitude" inevitably gets you.
This mess is lose/lose - the operator, CASA and ATSB look like a pack of idiots. None of us can tell if DJ is a sinner or a saint. The only lesson the pilot community can draw from all this is that there is no justice, so act accordingly. Needless to say, that ain't useful.
