Hopefully none of us will ever find ourselves in that situation.   

Would any of us potenially give up our lives for a stranger, with our own two children watching? If things did not turn out so well, we might be sitting here discussing how could anyone throw their life away and leave their children without a father.

By the same token (no pun intended), would any of us want our children to watch us stand by when another persons life is at stake?   What a tough decision.

It should also be noted that there were other people on the platform. Apparently this brave man was the only person who lept to help.
