How can you feel sorry for daredevils, they're practically asking to die?

I've been watching world's most amazing videos on spikeTV and these guys are so dumb. For example, they almost die doing a stunt and the majority of the time they try it again. They put they're lives on the line (very unlike firemen and policemen) so why should anyone care about them (family included) they don't care about their lives so why should anyone else.
