Warning Signs That Someone Is Capable of Murder

The article “Psychology and Criminal Profiling,” written by Junko Kotake in "Forensic Biology," warns that because there are so many reasons for a person to become a murderer, there are limits to warning signs that someone is capable of murder. Many who display all the signs of a potential murderer never commit a murder. The best that can be done, said Kotake, is to avoid people who display too many of the personality traits of a murderer.

Jealous or possessive behavior is not cute, Levin said in an interview in "Newsweek," and it is not a sign that he “loves you so much.” Jealous people are often abusers, which is another indication that a person is capable of going too far and committing murder. (See Reference section.)

Juvenile Delinquency

Criminal profilers often learn that a person who committed murder had a history of juvenile delinquency or other criminal behavior. Often, that person also has a history of academic difficulties or failures, Wood said. Profilers find that along with aberrant behaviors such as cruelty to animals or people, many convicted murderers had problems making friends and keeping friends. These people often get by in life by conning others and taking advantage of them. (See "Profile of the Sociopath" website in Reference section. 222)

These people, she said, can have a false sense of religion, but do not have empathy for others and their social behavior is a facade. They often feel superior to others, and blame others for all their problems or anything bad that happens to them; they take little or no responsibilities for their actions.
