I would argue that the price to get back into your god good graces is already very cheap. You can decimate an entiere town and just pay some gold, and bam you are redeemed.
In the final game I would expect there to be limits and escalations there. Maybe the price of redemption escalates with the number and severity of the crimes or there is a limit on the number of times you can be forgiven, etc. There's a number of ways in which this can be handled by Larian.
