The Justice Thought & System & its Morals?

Namo Buddhaya! Here are my questions regarding justice systems & their morals: > Would it be skillful & moral to report someone to a principle, a police > officer, or any sort of authority when someone is being hurtful to > others (such as killing, bullying, etc.), knowing that reporting them will most likely cause them suffering > e.g. expulsion from school, jail time, etc? > > And also is justice skillful, moral and is incarceration moral, > skillful in terms of the Dhamma? Metta!
