For me it doesn't matter if there is a life after, a god or none as my actions remain the same. Do my best in life and if there is a god that punishes that, so be it, if there is no god and it is fade to black, I lived a life of my best. People tend to dwell on what comes after life without thinking if there is life before death. They live for an unknowable future on rules they may never have truly considered. It is interesting to think about all of it of course though.
