How much would you risk for a stranger?

I noticed that Jonathan risked his life to help the little boy. Jonathan didn't need to help him at all; he had enough troubles of his own. As described on page 108, "more than once he staggered, but did not fall. Several times he put the boy down to rest." In this way, Jonathan risked his life and freedom in order to save the little boy. This made me wonder how much I would risk for a stranger. Under normal circumstances, I probably wouldn't risk myself for a complete stranger, unless I thought I had a good reason to and I believed the cause was right. However, extreme circumstances such as war, poverty or crisis do sometimes bring out an unusual kind of cooperation in people. Although I haven't experienced this, I believe it's true from what I know of history. Even though I don't know for sure, I think that everyone, including me, has the potential to sacrifice themselves for others, given the right circumstances. Truly, this is what I believe about my own ability to risk my life for a stranger.
