The original sin

[Stevemuss]

During all this lockdown I have started a conversation (via voice messages) with an openly Christian neighbor of mine about our beliefs. I asked her "why Jesus" because this is one huge part I could never understand about Christianity. 

Her answers are very centered on sin and mankind needing rescue (by accepting Jesus), leading back to the concept of original sin. She said that Judaism and Christianity have this in common, but so far my understanding was that in Judaism the consequences of that incident are not that any person being born "inherits" that sin, but that people start out innocent and without sin, but can, due to their own free will, commit sins in their lifetime. Are there any other interpretations in Judaism? Or is there any passage that suggests people need to be redeemed from that original sin?

Thank you!

There are a few passages which hint at original sin. “Surely I was sinful at birth, sinful from the time my mother conceived me” psalm 51:5. and Genesis 8:21

Psalm 58:3
The wicked are estranged from the womb;
These who speak lies go astray from birth

The Lord smelled the soothing aroma; and the Lord said to Himself, “I will never again curse the ground on account of man, for the intent of man’s heart is evil from his youth; and I will never again destroy every living thing, as I have done.

Jeremiah 17:9

he wicked are estranged from the womb;
These who speak lies go astray from birth

Not sure if this helps
