Not acting horrible because you're afraid of what God will do to you if you do act horrible isn't morality. It's covering your ass.
True morality has nothing to do with fear of consequences.
What is wrong with acting on an incentive? If a God exists, wouldn't you want him to punish evil people and reward good ones? And if fear of divine wrath produces repentance, why is that a bad thing?
If the only reason you don't murder people is your fear of being sent to jail/death row, that's not a good thing.
On the other hand, if fear of divine wrath does make people do good things/not do bad things, I'd say that's a pretty good thing.
