" Do-gooders are different because they are willing to weigh their lives and their families in a balance with the needs of strangers. They are willing to risk the one for the sake of the other. They-like anyone else, believe that they have duties to their families. But they draw the line between family and strangers in a different place. It’s not that they value strangers more. It’s that they remember that strangers have lives and families too. "
