Developing a Research Question

The issue of photography and objectivity is one fraught with ethical questions. Some of the most iconic, illuminating, moving, disturbing, and significant photos ever taken have been shrouded in controversy ever since their first public appearance. Many of them depict someone who is vulnerable to danger or even death. The question I wish to look into is in two parts: should photographers render aid to someone in imminent danger or seize the opportunity to give a potentially society-altering photo to the world? and, if the second choice is taken, who, if anyone, should publish or print the photo? Another related question is, what exactly characterizes the public demand for such photos? Observing life from a distance is something a competent photographer is good at.
