You must admit that any diving has its risks and unique skills and that some arenas have much more potential risk than others. There is no way around it, one must give acknoledgment where it is due for those that engage in the more complex diving ,,,,, where a cool head and a magestry of skills are the fence deviding those that have one safe surface for every dive and those that dont.
That's quite sad
Cave diving is dangerous, but I don't believe anyone can consider any type of diving the "pinnacle" it's all what you put into it. Each person has their challenges and with any scuba instruction it changes with instructor. In the end all diving is a lifetime learning endeavor. If you stop learning, that's when it'll bite you. Cave/open water/wreck/rebreather it'll kill you all the same.
