God is All-Loving, compassionate, merciful and forgiving
Start with a practical example e.g... a father who is displeased with his son and punished him and then goes on to punish the children of his son, and then his great grandchildren, etc. Will you consider this father a loving, caring and forgiving father?
Then how can you credit God such a heinous injustice of ascribing Adam's and Eve's sin to the progeny born even after thousands of years?
Children: kingdom of God belongs to the children: Mark 10:14, Matthew 19:14. How possible if the children are born sinners?!

People who were described as perfect in the Bible:
……………………. Noah was a righteous man , blameless in his time ; Noah walked with God. (Genesis 6:9)

There was a man in the land of Uz, whose name was Job, and that man was blameless, upright , fearing God and turning away from evil. (Job 1:1)
So how can they be sinners and be perfect at the same time?!
Every soul shall be paid in full what it has earned.
