EN48 has hit it on the head for me. Changing a syllabus, introducing post licence training/checks, IIMC avoidance training, etc. won't have a material impact on the statistics. IMHO, most of these accidents have much more to do with the pilot's attitude and personality. Even having been previously scared in seriously dangerous situations, I know pilots who habitually gamble with their (and their pax's)lives in similar avoidable situations. Their arrogance and ego take over and the "I'll be alright - been here before" attitude overules all training and common sense. It's just another challenge and each successful outcome pumps up the arrogance even more, fuelling over-confidence and the feeling of invincibility.
It would be interesting to compare personality profiles of those pilots who thought they were better than all the others who also shared that arrogance and paid the price. I don't think many would be surprised by the common theme.
RIP. My condolences to the pilot's friends and family.
