It occurs to me that these fellas were very well aware of the risks involved in their pursuits and were willing to accept death as a consequence. It is possible that their defiance of death during their extreme trek may have given them a sense of overconfidence in their abilities and skills. None-the-less, I do feel that people have the right to push their own envelope so long as they do not expect anyone to come rescue them.
