My opinion is that it can never be justified for a leader to oppress his own people. Leaders have a responsibility to their citizens to ensure their safety, security, and well-being. Oppressing one's own people goes against this responsibility and is a violation of human rights. It is not only morally wrong, but it can also lead to a breakdown of trust between the leader and the people, which can have long-term negative consequences for the country. Leaders should strive to protect their citizens and create an environment of fairness and justice, not one of fear and oppression.
