A Rattlesnake, if Cornered will become so angry it will bite itself. That is exactly what the harboring of hate and resentment against others is — a biting of oneself. We think we are harming others in holding these spites and hates, but the deeper harm is to ourselves. – E. Stanley Jones

We hate some persons because we do not know them; and will not know them because we hate them. – Charles Caleb Colton

There is no faculty of the human soul so persistent and universal as that of hatred. – Henry Ward Beecher
