Serious question: Why does one action not define a person? I know that's the usual party line, but why? Most of us have ethical boundaries, such as "Don't intentionally risk our friends' lives" and "Don't fuck people up for money." If you cross that boundary, even once -- or worse yet, those aren't boundaries for you at all -- that says a lot about you as a person. A 16-year-old knows that it's wrong to commit insurance fraud. They also know it's wrong to purposefully cause a car accident. It's quite telling, really.
