According to kohlberg, what is meant by "consensus democracy", and why is it necessary for moral development

Lawrence Kohlberg (1927-1987) is an American psychologist mostly known for his theory of stages of moral development, which adapts the theory previously conceived by Piaget.

His theory states that the basis to develop an ethical behaviour is by overcoming six different steps which involve a dilemma. Each stage requires more advanced moral skills to adequately solve the dilemma. Three levels of morality are distinguished in the stages, which chronologically are the following: pre-conventional, conventional and post conventional.  

In the conventional third stage is where the concept of consensus democracy plays its role. Consensus democracy is referred to the socially agreed standards which people try to resemble in their behaviour to gain acceptance and good opinions from his peers.
