Final answer:
According to the Biblical narratives, God expresses His disapproval for the sins of mankind through forms of punishment, including the Great Flood, expelling Adam and Eve from Eden, and causing death to certain individuals like Onan as a result of their sinful actions.
Step-by-step explanation:
The story you're referring to seems to draw upon Biblical narratives to suggest that God expresses his disapproval of the sins of mankind by various means of punishment or destruction. In Genesis chapters 6-7, God’s disapproval leads to the flood that wipes out all creatures except those on Noah's ark. In Genesis 3, following Adam and Eve's disobedience, God expels them from the Garden of Eden and denies them access to the tree of life as a form of punishment.
The scripture in Genesis 38:9 describes God's killing of Onan for his actions, perceived as wicked because he did not fulfill his duty to provide offspring for his brother. This illustrates yet another example of a divine reaction to human wrongdoing. Collectively, these accounts depict a God who responds to human sin with penal actions that serve as ethics lessons to the remaining or future humanity.
