Through violence you may murder a murderer, but you can’t murder murder. Through violence you may murder a liar, but you can’t establish truth. Through violence you may murder a hater, but you can’t murder hate.
Darkness cannot put out darkness. Only light can do that…. Difficult and painful as it is, we must walk on in the days ahead with an audacious faith in the future. When our days become dreary with low-hovering clouds of despair, and when our nights become darker than a thousand midnights, let us remember that there is a creative force in this universe, working to pull down the gigantic mountains of evil, a power that is able to make a way out of no way and transform dark yesterdays into bright tomorrows. Let us realize the arc of the moral universe is long, but it bends toward justice.
~ Martin Luther King, Jr.
