No and I don't believe anybody would be able to do it in such a situation (and even if, it's mostly because he'd be afraid of others' opinion or opinion of his parent whose life would be endangered). My own life is the most important thing to me, the most valuable thing I have and will ever have even if I were as rich as Bill Gates.
It's only stroking one's ego - "I'm so noble, I'd be able to sacrifice my own life". Even if you did, you wouldn't even be able to see the result of your noble deed. It's highly unhealthy and simply indecent to feel such strong attachment to whatever living being

I agree. Jesus/martyr syndrome in action.
