Sin, also for those who don't have faith, exists when one goes against one's conscience. To listen to and obey it means, in fact, to decide in face of what is perceived as good or evil. And on this decision pivots the goodness or malice of our action.

The great epochs of our life are the occasions when we gain the courage to rebaptize our evil qualities as our best qualities.

For our self respect depends upon our ability to make requital, for good or for evil.

Whatever harm the evil may do, the harm done by the good is the most harmful harm.

For all things are baptized at the font of eternity, and beyond good and evil; good and evil themselves, however, are but intervening shadows and damp afflictions and passing clouds.

To accept passively an unjust system is to cooperate with that system; thereby the oppressed become as evil as the oppressor. Non-cooperation with evil is as much a moral obligation as is cooperation with good.
