Final answer:
Someone who burns the flag because of the law is at the pre-conventional stage, while someone who burns the flag due to a loss of legitimacy is at the post-conventional stage.
Step-by-step explanation:
In this case, someone who burns his country's flag just because the law says he can is reasoning at the pre-conventional stage of moral development. This stage is characterized by a focus on obedience to authority and a fear of punishment. On the other hand, someone who burns his country's flag, because he believes that his country has lost its legitimacy, is reasoning at the post-conventional stage. This stage is characterized by a recognition that morality goes beyond what is legal and that principles of justice and human rights should guide moral decisions.
