If that God exists, the irony is that he would see right through them.
The idea isn’t to be evil and hateful until the last 5 minutes before death. I would even argue that that plan in itself would be another form of evil. It wouldn’t be true penance or regret, but instead, it would just be a way to save themselves at the last minute.
It could also maybe be seen as an insult to that God, to believe that he as an all-knowing deity would somehow not know their true intentions.
