It's not dangerous to perform a maneuver that's under control.

To claim the captain was incompetent, it would require to prove that all these violations of usual rules were unintentionnal.
That whole post is quite extraordinary (and worrying) but to pick out the two points above:
1) Aerobatics (in particular, barrel rolls), spins and test flying are hazardous activities where risk is controlled through application of mitigations in respect of pilot qualifications, experience, supervision, geographic location, etc - and perhaps most importantly in this context, numbers of commercial passengers: ie none.
2) Any captain of a commercial passenger flight who intentionally violates rules in the absence of extenuating circumstances is, by any reasonable definition, incompetent in their role. So I don't think any consideration of intent is necessary.
