In the above example, he did give the paladin said excuse, and doubtless would have continued with graphic examples as to the retribution that would be inflicted for that specific blow.
Really, there are two reactions I see as appropriate in this kind of circumstance. One: Assume the heretic is lying. Chuckle darkly at his obviously-misaimed attempt at threatening you, and point out that when you say Bahamut protects, you are not speaking in parable.
Option two: He's making practical threats he intends to carry out. He's a threat. Treat him as such. This involves a single clean bladestroke, not prolonged and pointless agony.
That being said, I say that if these actions are of sufficent import to draw the attention of one greater being, they are enough to draw the attention of two. If you do go the route of having a metallic dragon take an interest in his life, you should also have a servitor of another power (such as Bane, as suggested below) show up to the paladin at his darkest hour of chastisement, and say "Hey, you know that dude you killed? Bahamut thinks that you were wrong. And rather than tell you this face-to-face like a man, he pulled this passive-aggressive gorgon-droppings to 'teach you the error of your ways'. But Bane doesn't think you've erred. Bane thinks that you are bringing forth order and structure and justice, and has the respect for you to tell you to your face that he supports you. And if you ever decide that you might want to believe in a god that believes in you...well, you know where to find us."
