In the presented study, the main objectives of the freedom sentence are stressed. They are compared with the reality of statistics and practice in the imprisonment houses. Numbers of recidivists show the need for a better evaluation of the expected influences of this kind of punishment. Among various theories of criminality, the Cloninger´s biosocial theory is presented. Within these terms, an antisocial personality is characterized through the high level of novelty seeking, low level of reward dependence and harm avoidance. This model provides an explanatory background for understanding persistent social failures as well as low correctional potential of the prison. It turns an attention to the basic problems of freedom and determinism, which are discussed at the closure of the paper.
