The positives of prison rehabilitation are education and psychiatric treatment. The negatives of prison rehabilitation are deeper involvement in crimes and learning of new crime methods.
The main purpose of rehabilitation is to prevent prisoners from going back to prisons for another crime after being released. After experiencing prison life, some prisoners avoid going into prison again. Education programs, which include degree programs and classroom environments are provided to prisoners. Some people who commit crime are hardly educated. After getting education in prisons, they turn over a new leaf, according to some studies. Some prisoners mix with other prisoners and learn new methods, which they use to commit worse crimes after being released.
