Jesus did not comment on the subject to my knowledge. Jesus preached compassions and forgiveness. If I understand your implications correctly, I believe you may be assigning the statements of of some Christians to Jesus, but Jesus himself did not condemn people for sins.
If that is so, then I don't see how Jews avoid damnation. For that matter, the vast majority of everyone who has ever lived and died is doomed to Hell.
Can you reconcile that with the idea of a loving, merciful deity?
