I’m a bit unclear about what you mean. I think the media’s tendency is to generally focus on the criminal’s history and motivations way more than the victim’s. Also, entire fields of academic study exist just to examine why people commit crimes.
I mean that on local news (and many times on national news), every day there is a story talking about how a victim was a great person and accomplished many things. Every story ends up being an obituary. Meanwhile, there will be very little said about the criminal, unless they find out that the person committed another crime. So, people will start talking about how horrible the criminal is and how they have committed such atrocities, but they won’t know what might have led the person to do it.
I’m aware that sociologists, psychologists, anthropologists, social workers, criminologists, etc. all study criminals, but I think that it is important for society to know what leads to criminal behavior. It might give people a wake-up call about how they treat their family or classmates. It might show them that they need to pay attention to how some people behave or what people say. It would make society better if people could understand not only the great loss of the victim, but what really caused that loss.
