That comment reminded me of an article I read about deaths diving the Andrea Doria. The skipper who had to pull the bodies out was quoted as saying (I paraphrase): "They say diving is not a competitive sport. But they're wrong."
For some, diving's a competitive sport, for sure. Proving oneself, gaining recognition, thrill-seeking, and tempting fate may also be motivations for some divers.
This thread, as disarming and unassuming as it is, has been interesting because the true underlying motivations have occasionally been revealed.
I've found those motivations fascinating, even instructive.
