Yes, there are some people who thrive on risk and will do things like jump off a mountain in a wing suit just for the thrill of it. That doesn't mean making that sort of personal recklessness legally mandatory for employment is a good idea.

This sort of personal liability OP is proposing would just ensure the security industry is dominated by highly compensated compulsive gamblers because nobody else is insane enough to take the risk. It's an absolutely ridiculous idea.
