Within level I: Preconventional morale, in Stage 2: the purpose and exchange.
During this stage a new standard of judgment emerges: Justice.
In this sense, it is thought that if someone has a reason to make an action, the individual must be judged on the basis of that reason and not by the arbitrary will that the figure of authority possesses.
Moreover, the individuals who belong to the second stage no longer believe that punishment arises immediately after the bad action, but that doing something bad implies doing something bad to someone, and this supposes a punishment that responds to the crime.
