I never worry about things like this. Graham is dead and gone and he gets judged just like everyone else. God gets the last laugh. Do you not find it amusing the thought of all the people who accepted Jesus because of him to claim it was made possible by the devil? Dig all you want anon, shine light into the dark places, but remember above all that God is ultimately in control. Just as it is written "You meant evil against me, but God used it for good." This is a reoccurring theme in life where bad intent sometimes ends up having a positive impact.
