"The world is a dangerous place, not because of those who do evil, but because of those who look on and do nothing."         Albert Einstein

"There are a thousand hacking at the branches of evil to one who is striking at the root."         Henry Thoreau

"Men never do evil so completely and cheerfully as when they do it from religious conviction."         Blaise Pascal


He who does not punish evil, commands it to be done. Leonardo da Vinci

If only it were all so simple! If only there were evil people somewhere committing evil deeds, an it were necessary only to separate them from the rest of us and destroy them. But the line dividing good and evil cuts through the heart of every human being. And who is willing to destroy a piece of his own heart?--Alexander Solzhenitsyn (The Gulag Archipelago)

If you know that a thing is unrighteous, then use all dispatch in putting an end to it--why wait till next year?--Menicius

There is no evil that does not offer inducements. Avarice promises money; luxury, a varied assortment of pleasure; ambition, a purple robe and applause. Vices tempt you by the rewards which they offer.--Seneca

When you use bad means to get good ends, you ruin the ends. You find evil in the end that you introduced into the means.--Joseph Jean Lanza del Vasto ("The Principle is to Unity of Life" in Peace is the Way)
