A few years ago, a fuel truck caught fire just before emptying its load in a gas station. The driver jumped out and ran away. A guy was driving by and saw what happened. He left his car and drove the truck away to an empty area

That case is a bit more black & white than what the lady did. Even if this guy died during his heroic effort, his kids were at home with their mom (or school) at that moment. Not near the scary incident.
