Evil is natural or moral. Natural evil is any thing which produces pain, distress, loss or calamity, or which in any way disturbs the peace, impairs the happiness, or destroys the perfection of natural beings.
Moral evil is any deviation of a moral agent from the rules of conduct prescribed to him by God, or by legitimate human authority; or it is any violation of the plain principles of justice and rectitude.
There are also evils called civil, which affect injuriously the peace or prosperity of a city or state; and political evils, which injure a nation, in its public capacity.
All wickedness, all crimes, all violations of law and right are moral evils. Diseases are natural evils, but they often proceed from moral evils.
