That seems to be what happened to Ian Paisley. The bastard actually managed to squeeze out a bit of truly Christian behaviour at the end of his life, after a lifetime of creating conflict based on hysterical prejudice. I am always touched by such things: it makes you feel that perhaps as death approaches there is a clarifying of thought that make some people realise they have only one more shot at being remembered as a force for good. The deathbed conversion, if you like.
I always thought Paisley was straight out of Spitting Image, especially given his strong accent. He used to refer to the Pope as the 'Whore of Rome', if I remember correctly: one Christian to another. Don't they just love each other.
