Robertson has, in the tradition of other mindless frauds like Falwell, proven himself to be a total schmuck in response to natural disasters. The choice of one example was hard, but I think this seems to demonstrate his logic:
Something happened a long time ago in Haiti, and people might not want to talk about it. They were under the heel of the French. You know -- Napoleon the Third or whatever. And they got together and swore a pact to the devil. They said, 'We will serve you, if you'll get us free from the French.' It's a true story. And so the devil said, 'OK, it's a deal.' And they kicked the French out -- the Haitians revolted and got themselves free -- but ever since, they have been cursed by one thing after the other.To the boring question regarding bad things inflicted on good people, people are rarely willing offer the simple truth (without getting into the science of it), which is that we live on planet in which such things happen. But if we are willing to blindly embrace the doctrine that we live in a world supervised by a designer, it becomes understandably difficult to maintain the falsehood that such a god is in anyway benign, much less loving. They're not willing to surrender the idea that this deity has a vested interest in our wellbeing, and are then forced to place blame upon the people who built their homes right in the path of God's divine tornado. The absurdity in this proposition need not be elucidated. That said, logical invalidity is lesser in the view of classical Greeks, whose gods were seen as spitefully capricious and indifferent. Any other view simply doesn't conform with reality.
