In the Dark Knight, Joker tells Batman that to get the truth he will have to break his one rule. In essence he is telling Batman he would have to kill him to stop him. While Batman ultimately is able to beat the Joker, he still loses.
We as Conservatives have one rule we live by. We refuse to destroy our morals and principals for anything. We understand that while everything goes to hell, the ability to look in the mirror in the morning and not be disgusted with what you see is extremely important. Our problem is we fight those that have no such qualms.
