Weighting the hurt against the benefits and justifying that hurt can make the right way apparent. Journalists want to report stories the public wants to know and not just those the public wants to read. We feel obligated to inform people about every important event occuring in their communities. Truth and ethics are not similar, you wouldn't want to show a victim of rape aggression on the national television, because even if what has happened to her is true, it's not ethical to interfere in somebody's personal life. Each ethical situation is unique, and journalists must consider each individually, trying to balance the conflicting values.
Every journalist is free to decide what is wrong or right, ethical or unethical.
