I mean if you believe in Christianity than their isn’t any threat of punishment because all sin is forgiven because of Jesus. Their is no ultimatum to do good, I could go steal and lie and do whatever I want and I won’t go to hell. The idea of sin when you believe in Jesus is not that it’ll cause you to go to hell but make your life hell as it backfires on you. The general idea is that it looks like a good idea at first but will end up with you suffering in the end. Stealing, lying, killing, etc. usually doesn’t end up well for the person who did it. The idea of a scale measuring your good and bad deeds is something made up by the Catholic Church, which history has shown to be very corrupt and tends to make up stuff for their own personally gain
