It is extraordinary to think how one man can have had such significance in so many lives. This quote provides valuable insight and perspective:
“I mourn the loss of thousands of precious lives, but I will not rejoice in the death of one, not even an enemy. Returning hate for hate multiplies hate, adding deeper darkness to a night already devoid of stars. Darkness cannot drive out darkness: only light can do that. Hate cannot drive out hate, only love can do that.” Martin Luther King Jr.
According to one source, the quote is a hoax (though no proof is offered). It is a beautiful quote, whoever penned/said it.
