Paladin

"None of that, 'Oh well if you're truly sorry, there's nothing I can do," horseshit. No, he coup de graces your ass because he's a goddamn Paladin. His job is killing evil. You know what his job doesn't entail? Being a sympathetic ear for every whiny NE or CN or LE douchebag who's only being evil because the world is unfair to him or every punk that lets his own dislikes or laziness overcome his own personality. You know what unfair is? Being able to know what kind of person everyone is before you even talk to them. Smelling evil so potent on a motherfucker that you want to sink your fingers in his chest and pull that tar out until the screaming stops. Having the psychotic urge to murder people that you've never even met, for the sole reason that your God decided that you ought to be his right hand without your choice in the matter, that's unfair.
But unlike Evil McBlacknails over there, that Paladin puts on his helmet, sharpens his sword, and then continues walking through crowds of people day by day, resisting the urge. Seeing evidence of injustice so black it makes him sick. Seeing murderers and rapists walk the street, watching good men hang as evil ones pull the lever. Saving his righteous violence for when the situation exactly, specifically, precisely calls for it. Surgically removing that which is most evil. Because he's a Paladin. And if he gave in to the urge, what would he be? Who will right the true wrongs if not he? Paladins don't fall, no sir. They break, and the world falls on top of them, because they were the ones keeping it up."

"A Paladin stands between right and wrong.
Between the innocent and the corrupt.
He must be cunning, fast, thoughtful and kind.
He is the hands of good on earth.
Above all, he is a shield for those with no other armour."

He is sworn to valor.
His heart knows only virtue.
His blade defends the helpless
His might upholds the weak
His word speaks only truth.
His wrath undoes the wicked.
