Evil exists to glorify the good. Evil is negative good. It is a relative term. Evil can be transmuted into good. What is evil to one at one time becomes good at another time to somebody else.

Truth uttered before its time is always dangerous.

Kindly words do not enter so deeply into men as a reputation for kindness.

Let not a man do what his sense of right bids him not to do nor desire what it forbids him to desire. This is sufficient. The skillful artist will not alter his measures for the sake of a stupid workman.
