I've never really lived a dangerous life, like any guy I've had my share of thrill seeking adventures most of them right around the time I turned 30 but nothing too dangerous. I went sky-diving once and that's considered dangerous by a large number of sane and rational people but it was also a lot of fun. I think getting on flight 815 was pretty dangerous but not an actively dangerous decision. So I'm not sure that would apply.
I think almost every decision I've made since we crashed could be considered dangerous depending on how you view the situations. Some people would say trusting Kate is dangerous; luckily I'm not one of those people. I know trusting Sawyer is potentially dangerous and that's probably why as a general rule I don't take him at face value. Actually if you want to get technical trusting anyone on this island could be considered dangerous.
Every day is dangerous here. Walking into the jungle is dangerous; there is a monster, the others, animals, rocks to fall from and everything else that could happen on an island or in a jungle. There are numerous things that happen here on a daily basis, situations we get thrown into and situations we throw ourselves into.
I guess if I had to pinpoint one extremely dangerous thing I've done since we crashed on this island it would be running into the jungle half-cocked looking for John Locke. Sure there were plenty of instances after that, which might be worse in certain ways. Like going after Michael, which almost got Kate killed, but when I went after John I wanted blood, it was dangerous on more levels than just psychical danger, emotional danger was there too. If I'd found him that day, covered in Boone's blood, I don't know what I would have done or what it would have done with me.
