That is patently ridiculous and taken to the extreme and you know it. We are talking reasonable possible situations (not world events) that you may find yourself in. And yes, if I had a choice to save an entire building or just my kid, it's my kid every time. I fail them morally if I do not. I'm not responsible for other people's family, just my own. Now... if I could save my kid and everyone else, then yes. But my kid first.
