What is an example of classical theory in crime?

An example of classical theory in crime is Cesare Beccaria's concept of deterrence, which posits that individuals make rational choices to commit crimes based on a cost-benefit analysis. Beccaria argued that the certainty, swiftness, and proportionality of punishment would deter criminal behavior. This theory emphasizes that people will refrain from illegal activities if they believe the potential punishment outweighs the benefits of the crime.
