There is no “original sin” in Judaism, and Jews are not in fear of “being saved”. Also, one is responsible for one’s own sins. The idea of a corporeal god-son taking sin and self sacrificing is, as I understand, totally alien and contrary to God in Judaism.
(And if Jesus was the son of God, but also God, how could he be killed unless he chose that ending for himself? For isn’t God all powerful and all knowing? )
How could a god be “all-knowing”/perfect without being self-aware/possess cognizant apitude? God made humans above the animals after all (Let US make man...) and also judges them. I thought Torah worshipers prided themselves on intellectualism. Is your god confined to physics/time/space and is ignorant on a most precious creation that “it”, by default mind and all rationality mind you, judges unrighteously?
The more common "Jewish" or rather belief is that a soul goes through Purgatory for up to a year, although the time could be as little as five minutes ( or not at all, in the cases of very righteous individuals). While there, the soil burns with shame at the reality of his/her life, seeing all the consequences of every action (or inaction), word, thought, missed opportunity, etc.
The idea of a corporeal god-son taking sin and self sacrificing is, as I understand, totally alien and contrary to God in Judaism. -- not really, the first Christians were all Jews. In fact really until 70 AD Christianity was a Jewish sect
The idea of a corporeal God-son is there in the Tanakh (Daniels "like a son of god" for instance) and taking sin - a sacrificial lamb, and self-sacrificing - Samson among others
Don't mix up Pharisee-Judaism with overall 2nd temple Judaism
Net net, Jesus did chose that ending. The sin against the perfect one requires the perfect sacrifice.
