Throughout the essay classical theory, Cesare Beccaria, and deterrence has been explored in relation with one another. The manuscript disclosed that individuals are rational beings who pursue their own interests, trying to maximize their pleasure and minimize their pain. Classical theorist Cesare Beccaria determined that if the justice system reformed such as using rational penalties for crimes committed then such behavior could be deterred. The deterrence theory proved that people do refrain from committing crimes because of the fear of punishment. Therefore, the deterrence theory most fully reflects the ideas of classical theory.
