Criminal Justice Goals

What do you think is the most important goal of the criminal justice system? Why?
I believe the most important goal of the criminal justice system is deterrence. By deterring people from crime, society is eminently safer. The economy would definitely be improved, as shoplifting, burglary, and other types of theft would occur less frequently. The costs involved with arson, mass and serial murders, and the other various crimes would also be less troublesome for the local and federal governments. I also believe that the collective emotions and feelings of society would be more positive, as there is definitely less fear. Overall, I think deterrence in criminal justice is common sense - stop crime before it happens so it does not become problematic
