troubled to troublesome

In light of recent events at Virginia-Tech, the media has been covering a huge range of topics dealing directly or indirectly with Cho Seung-Hui. Roommates have come forth, bringing stories of a 23-year old who was difficult to relate to, who received tutoring in English and his writing displayed hate-induced threats to an abusive father; the police received complaints about his harassing girls via instant messaging, the telephone, and in person; he was admitted to a mental hospital in 2005 because he seemed at risk for suicide. All of these behaviors meet the criteria, the checklist, if you will, for a criminal, for a depressed person who becomes a killer, taking his own life and at least 31 others students' lives. To explain just how a 23 year-old man from South Korea could commit such a heinous crime, criminologist Jack Levin from Northwestern University explained how he met the criteria, but that many adolescents and young adults meet the criteria. He concluded by saying something that should be heard by all,

There is one thing that I think is very important to emphasize. We should be caring about people who are troubled long before they become troublesome. We should reach out to people not to punish them, but to give them our concern, our caring, and then we might even prevent a murderer too in the process.

Let us not be consumed by the media, by speculation, by unimportant sidenotes; let us move forward and reach out to others, as Jack Levin suggests.
