Nothing is more costly, nothing is more sterile, than vengeance.

Duty and prudence alike command, first, that the germ-centres of hatred and revenge should be constantly and vigilantly surveyed and treated in good time, and, secondly, that an adequate organisation should be set up to make sure that the pestilence can be controlled at its earliest beginnings before it spreads and rages throughout the entire earth.

A small revenge is more human than no revenge at all.

Always stay gracious, best revenge is your paper.

I love to remember my enemies and I love to get my enemies. I had some enemies. I had people that really I helped a lot. And when I needed the help, in some cases, they were not there for me.

Wretched are those who are vindictive and spiteful.
