Serious research into the psychology of those who commit crimes,
particularly repeat offenders and serial criminals, may at times
seem pointless. Lock them up and throw away the key? Lock them
up, yes. But insight into the motives and strange logic of these
criminals may not only help authorities incarcerate offenders, it
may, in the future, help keep the most dangerous locked
away from the general population and possibly help spot those
which can never be rehabilitated.
