Why are lawyers so risk averse instead of active participants?

Recent local media articles show shocking examples (at least in the US) of individuals and corporations acting very conservatively to the legal and business environment.

For example, in Florida a life guard was fired for saving a man's life outside of the life guard's permitted boundaries. Yet Florida recognizes corporations as legal entities and has a good Samaritan law on the books. Lawyers know the right thing to do, but consistently advise their client on the legal thing to do.

So what are you, an active or risk-adverse attorney? Why have you chosen that path? Which do you think is the best path? Which path would you rather take?
