" You weren't just furious at those evil [men]...but at evil itself, at the fact that evil exists, infuriated by the very idea of evil allowed to go unrestricted, unchecked. ...But this righteous anger seems always to lead to an irresistible compulsion to act regardless of the risks, and not merely a compulsion to act, but to do the right thing. We can exercise freewill and turn away - but only at a cost in self-respect that's intolerable. "

― Dean Koontz , By the Light of the Moon
