Revelry in the death of any being for any reason reveals the most pathetic, empty aspects of humanity. Murder, no matter it claims to be in the name of, is always a cause for compassion. These short statements make a huge impact, and seem pointedly relevant given recent world events.
"An eye for an eye leaves the world blind"
"I will 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
