What is the main objective of criminal law?

The primary aim of criminal law is to protect the personal security of citizens. This branch of law is designed to maintain public order by prohibiting harmful behavior and ensuring that individuals who commit offenses are held accountable. By defining what constitutes a crime and establishing penalties, criminal law serves to deter individuals from engaging in conduct that could harm others. This protection extends to safeguarding individuals from threats to their safety, which is a fundamental aspect of living in a society.

The other options deal with different areas of law or objectives that do not align with the core purpose of criminal law. For example, defining private disputes pertains more to civil law, which handles conflicts between private individuals. Regulation of business activities falls under administrative or corporate law, focusing on the conduct of business within legal frameworks. Promoting international relations typically involves diplomatic or international law, which governs the interactions between nations. Therefore, the emphasis of criminal law on safeguarding personal security distinctly sets it apart as the correct answer in this context.
