There is a very mature and compassionate response to Pat Robertson's remarks on the tragedy at Haiti found here. Thanks to the pastor of my church for the link.
Now, as a Mormo-Wiccan I feel I must respond. This is purely a Mormo-Wiccan perspective and not the views of any other faith.
Do not blame Satan for the results of a deal you may have struck with him. "The Devil made me do it" may be a reason for children to take cookies without permission, but as adults we have to admit our complicity in our own deals. Satan does not just enter into a deal. He makes you take your time. Too many people reach out to in a moment of desperation. Realizing that this scenario could lead to bad publicity, Satan has a customer relations policy that would shame auto dealers.
The typical soul exchange scenario is more like a relationship. He has coffee with you. He gets to know you. Only once he truly understands your proposal will he begin the negotiation. He bluntly states what he will require as payment. Usually, it is your soul (standard terms apply). But quite often it is only your first born or the failure of your marriage. One popular for most of humanity is to be thought of as a villian or infamous tyrant. But again, he makes that clear in a blunt contract. One of his newer policies is that he makes you sleep on it. No customer is allowed to sign on the bloody line without first waiting an entire 24 hours before signing (or one episode if you are Jack Bauer).
So, when there is wailing and gnashing of teeth later, it is really buyer's remorse. But we want this clear - the Devil made the terms clear. You sold the Devil your soul and when payment is due, PAYMENT IS DUE.
I leave you with this informational diaglog that Satan paid to have placed in the great movie "Oh Brother, Where art thou?".
Ulysses Everett McGill: What'd the devil give you for your soul, Tommy?
Tommy Johnson: Well, he taught me to play this here guitar real good.
Delmar O'Donnell: Oh son, for that you sold your everlasting soul?
Tommy Johnson: Well, I wasn't usin' it.
