The boulder problem was super sketchy. His "successful" climb looked like it could have easily been a coin toss whether he lived/died on that section. It was stomach turning to watch -- and many of his climber friends couldn't watch either.
You definitely don't need/want a lot of these personality types in a population, but I can't help but think they help advance the art of the possible. Would I personally want one as a child, spouse, or family member? Absolutely not.
It's probably less risky than free soloing, but I can't help but think of the risks that Nurburgring test drivers take. I was watching Chris Harris' video on the GT2 RS MR and they had the driver that set the new lap record at the ring. I clearly remember him mentioning having to put the fear/consequences out of his mind whilst he did 6:40 lap in production car. If you've not seen the video I'm referring to, give it a watch -- incredible stuff:

And here's the Ring lap footage. The driver repeatedly goes over 175mph -- mind blowingly fast on that track:
