Treachery
It is time to fear when tyrants seem to kiss.
Shakespeare.
Men are oftener treacherous through weakness than design.
La Rochefoucauld.
In general, treachery, though at first sufficiently cautious, yet in the end betrays itself.
Livy.
There’s neither honesty, manhood, nor good fellowship in thee.
Shakespeare.
There is no knife that cuts so sharply and with such poisoned blade as treachery.
Ouida.
There is no traitor like him whose domestic treason plants the poniard within the breast which trusted to his truth.
Byron.
Deliberate treachery entails punishment upon the traitor. There is no possibility of escaping it, even in the highest rank to which the consent of society can exalt the meanest and worst of men.
Junius.
