Concern for the plight of others is normal; it is part of being human. People recognize what it means for someone else to be cold or wet, or face thirst or hunger. Accounts of what we should do as a society have a place for empathy. The over-arching political philosophies, conservatism, liberalism and socialism are built around ideas of what responsibilities citizens have (and do not have) to each other, though this does not mean it is easy to reach agreements about how to provide shelter, and sustenance to those in need.
