I thought it was hilarious that his son said that he expected it to be just like the other eight times, where he went home, got sick and recovered. That's like saying you were surprised that you got hit by a car, when every other time you crossed the freeway with a blindfold on you managed to make it. It wasn't even the first death in that church from handling serpents.
There is no cure for stupidity of that magnitude, except for the obvious, death.
