He wants feeling.

From some traits of his character which have lately come to my knowledge, he seems to have been so hackneyed in villainy, and so lost to all sense of honor and shame, that, while his faculties will enable him to continue his sordid pursuits, there will be no time for remorse." With this single expression of measureless contempt, Washington let Arnold drop from his life.

The first shock had touched him to the quick, although it could not shake his steady mind.

Reflection revealed to him the extraordinary baseness of Arnold's real character, and he cast the thought of him out forever, content to leave the traitor to the tender mercies of history.

The calmness and dignity, the firmness and deep feeling which Washington exhibited, are of far more interest than the abortive treason, and have as real a value now as they had then, when suspicion for a moment ran riot, and men wondered "whom they could trust." The treason of Arnold swept like a black cloud across the sky, broke, and left everything as before.
