Lesson Highlight: "leaving him half dead"

In "Biblical Perspective" Dr. Gordon Snider writes:

Shepard notes that the dangerousness of this road was legendary. The man could not possibly have not known his danger! Thieves . . . stripped . . . and wounded him. The violent nature of these men is clear from their actions. They were not petty thieves, but hardened criminals without mercy. Leaving him half dead. Luke wanted the reader to understand the desperate plight of this traveler. Unless someone gave aid soon, death was certain.

It is possible to read this story without truly visualizing how hurt this man was. Art, such as this picture, might shock some for its somewhat graphic nature.
Discussion: Do we truly understand the "desperate plight" of this man? Do we truly care for the plight of others around us who are in need?
