Evil is always in the service of the greater good.

 

Rudolf Steiner:  "...a truth which should be engraved in the human soul as a lofty moral maxim: When you see something evil in the world, do not say, Here is evil — that is, imperfection; ask, rather, How can I attain to the enlightenment which will show me that on a higher plane this evil is transformed into good by the wisdom of the cosmos? How can I learn to tell myself: Here you see naught but imperfection because you are as yet unable to grasp the perfection of this imperfect thing? Whenever man sees evil he should look into his own soul and ask himself, Why am I not yet able to recognize the good in this evil that confronts me?"
