Revenge, at first though sweet,
Bitter ere long back on itself recoils. John Milton.
This was the most unkindest cut of all. Julius Caesar.
Wisdom and goodness to the vile seem vile. Shakespeare.
The wicked plotteth against the just. Psalms.
The black destroyers, the red torturers
Shall vanish—they like smoke shall disappear.
Mother Armenia.
Women always find their bitterest foes among their own sex.
J. Petit-Senn.
