Hey now. :-) Let's not forget she was an adult too and responsible for her own safety as much as he was.
"They had two sandwiches, four cookies, two chocolate bars and two cans of juice."
She could have just as easily packed an emergency kit for the car just as easily as he.
They were not prepared, they made some bad choices, and she paid for it. I'd say that was *their* fault, not *his* fault.
