Final answer:
An individual seeking to modify an unjust law for fairness aligns with the post-conventional stage of Kohlberg's theory of moral development, which is focused on abstract principles of justice and human rights.
Step-by-step explanation:
An individual who wants to modify a law if it is not fair to a particular group is likely operating within the post-conventional stage of Kohlberg's theory of moral development. At this level, individuals think about morality in abstract terms and recognize that legality and morality do not always align.
They evaluate the fairness and justness of societal rules and laws and are willing to challenge and change them if they do not serve the common good or respect fundamental human rights. Lawrence Kohlberg suggested that such moral reasoning is indicative of the highest stages of moral growth, where value judgments are made based on principles of justice, human rights, and social welfare.
For instance, during the 2011 Egyptian protests, hundreds of thousands demonstrated against government corruption. This collective action exemplified post-conventional morality. The protestors recognized that while their government's authority was legal, it was not morally just, prompting them to seek change.
