There is nothing I can say that has not already been said. I will spare you any empty repeats of condolences. I will simply say what I feel I should. 

Lower your head, and charge forward. They have made themselves as less than human, and are not to be feared, but punished. Would it not make it worse for you, I would take their blood upon mine hands. 

Bring them to task, and let them suffer your pain one thousand fold. In your defiance of their fear mongering you will find your courage, with each step of your charge becoming more sure. Do not falter, do not wain. Let them fear the reprisal the have brought to themselves, for you should not abide inaction.
