Good and evil exists in all of us.
To keep evil at bay would require extreme determination and vigilance (and education) on the part of all of humanity for all time, as evil doers are so determined and vigilant in their pursuits (and spreading of disinformation). When you cut a head off the Hydra another two spring forth to take its place.
That's why we must get down to basics. Only PEOPLE have rights. All governments and other organizations, when acting as organizations, only have duties, and privileges... which are subservient to rights. This is why the American system of government has the 7th Amendment, 12-person jury. If the jury is exercised in its basic, common law form, with regard to the case at hand, the common law jury can rule any way it wants: declare the "defendant" innocent or guilty; declare the "plaintiff" innocent or guilty; declare the law null and void in this case; determine the sentence; and anything else it wants in the case at hand.
This keeps government from going nuts, and taking rights away from the people.
Read the 7th Amendment. If you are ever a defendant for anything, require a 7th Article of the Bill of Rights, common law jury trial. Ask if the judgment will be able to be appealed. If it can be appealed, it is not a 7th Amendment common law jury trial.
