I think kaffirs can say ok ish things but still act wrongfully. The word is said to mean one who conceals and is concealed from the truth, covered, like how the Qur'an says about a covering over hearts so they can't really understand or do the right thing except unintentionally or on occassion. That Iblees which seems to stem from the word despaired as in who causes one to lose hope (by offering false hope that is demonstrated as a mirage like in the Pagan Battle against Muslims) and loses hope or has lost all hope so is on a spiral of evil counsel all the way to hell. He too is concealed from the option or truth of forgiveness, repenting truly and turning back. The Qur'an says he is a race of being called a jinn which were made before human beings out of a different central substance but is thus as real as a person is real but made out of fire rather than mud or clay. He seemed to have wanted jinn to be the special dominant species rather than put under the dominion of the human mud people. There were no 'pagan' battles against anyone, since Muhammedians are pagans themselves. But if we speak of Eblees as a devil, which I state is not correct, but if we do, there is no way such force can be deluded either. I am just trying to make others think, if there really is a bad guy whose sole purpose in life is to distract you, or perhaps it is you who are deluded? This is also the question of responsibility. Once we are responsible for our own actions, and do not try to blame them on somethign else, this is when we become thinking beings.
