Evil is the opposite of good or godly, and evil acts live on in memory even when the person responsible is gone. There is plenty of evil in the world today, but it can be combated by those who do good. Anyone with evil intentions will not care about who gets hurt, they only worry about their selfish desires and care not for what others think or feel.
The devil is in the details, and everything we do in the military is a detail
One seldom recognizes the devil when he has his hand on your shoulder
Resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also
Never open the door to a lesser evil, for other and greater ones invariably slink in after it
