Another faulty understanding. Sinning is the true human nature (and not only human) because it is natural for one to make errors and wrong decisions. That is why to punish someone beacuse he makes a mistake is utter foolishness.
On the other hand we usually reap the harvest of our actions and because we want to blame someone for our errors, we attribute it to a “Punisher God”.
This is the foolishness of human religion.
