I think it's a duty as a human being to do your best to do that. I'm not saying that I have the guts to go into a burning building that's about to collapse, to search for somebody, but if I saw the person alive in there, and I could physically get to them (that is; I have at least a chance to survive it), my answer is yes I would. Sadly I had to watch someone burn alive in a car fire, as it was too late to get anywhere near them, and they were already hurt to the point they couldn't have lived. All I could see in the flames was a body moving a little, and it looked like they puffed up as to take a deep breath, and they disappeared. It was a small car that had crashed underneath a tanker truck on Hwy 210 east of Los Angeles in the middle of the night about 8 years ago. Seeing something like that, makes you KNOW that you wouldn't ever allow it to happen if you have any possibility whatsoever to stop it.
