I don't expect Hollywood writers to understand exactly what it is to be a "born again" Christian, but it might have been helpful to speak to some theologians before writing this script. I have never heard a single pastor preach that God's forgiveness releases you from the temporal consequences of your actions. In fact, Christ himself, when asked if it was legal to pay the tax, responded with "Render unto Caesar, that which is Caesar's and render unto God, that which is God's." In this context, the punishment of the body under the law for the murder was "that which is Caesar's" while the punishment of the soul, is "that which is God's".
At the Crucifixion, Christ was raised on a cross between two thieves. One who mocked him and one who sought and received his forgiveness. But both still died on their crosses. If God's forgiveness was intended to spare the forgiven from human punishment, the "good" thief should not have died.
If I max out all my credit cards gambling, then confess my sin of gambling and change my ways, would any reasonable person insist that the credit card companies should wipe out my debts? Of course not! The premise here is no more reasonable, and probably really reflects a bigoted view from the writers, of those who call themselves "born again".
