This doesn't see right. There are laws in which we must follow to protect individuals from being mistreated or having cruel and unusual punishment inflicted upon them.
Prison inmates, are considered some of the most "disturbed" people in society. Most of the inmates have had too little discipline or too much, come from broken homes, and have no self-esteem. They are very insecure and are at war with themselves. Most inmates did not learn moral values or learn to follow everyday norms. Also, when most lawbreakers are labeled criminals they enter the phase of secondary deviance. They will admit they are criminals or believe it when they enter the phase of secondary deviance.
Next, some believe that if we want to rehabilitate criminals we must do more than just send them to prison. For instance, we could give them a chance to acquire job skills; which will improve the chances that inmates will become productive citizens upon release. The programs must aim to change those who want to change. Those who are taught to produce useful goods and to be productive are "likely to develop more self-esteem and possibly more respect for others. This kind of program would provide skills and habits and replace the sense of hopelessness that many inmates have.
In addition, another technique used to rehabilitate criminals is counseling. There are two types of counseling in general, individual and group counseling. Individual counseling is much more costly than group counseling. The aim of group counseling is to develop positive peer pressure that will influence its members. One idea in many sociology texts is that group problem solving has definite advantages over individual problem solving. The idea is that drawing from the experience of several people with different backgrounds can derive a wider variety of solutions. Also one individual's problem might have already been solved by another group member and can be suggested.
