What punishment concept says the guilty should be punished according to what they deserve no more and no less?

The punishment concept that states the guilty should be punished according to what they deserve, neither more nor less, is known as "retributive justice." This philosophy emphasizes that punishment should be proportionate to the severity of the crime committed, reflecting a moral balance between offense and consequence. Retributive justice seeks to ensure that offenders receive their "just deserts," reinforcing social order and moral accountability.
