Good by defination has to be tolerant. Intolerance, the lack of empathy, IS one of the definations of evil.
As a DM (which is mostly what I do btw), if a paladin in the party attacked or killed someone simply because that creature or person detected as evil, I'd likely change the paladin's alignment. If such a person were to kill someone because of a divination, and not based on any witnessed acts of evil, how could you not define that as evil? Simply having an evil alignment doesn't mean that a person has actually commited any acts of extreme evil (ie: murder, rape, etc). It could be simply a greedy miser, ala Scrooge. You think a paladin would be justified in killing such a person? Why would it be any different if it were a kobold?
Also, I don't see why a lawful good cleric and a lawful good paladin of the same god would behave differently in such a situation. Paladin's follow a "warriors" code of conduct, but this code of conduct is there to re-enforce the established ethos of that religion (which the cleric is also bound to follow).
