According to some Jews, they believe that no one can die for the sins of another:

Ezekiel does prophecy a time when everyone will die or live based on their own sin or repentance.  Yet, that must be in the future.  Does not everyone die now??  And what about the Hebrew sacrificial system?  Did they not use animal sacrifices to atone for their sins?  Is that not one dying for another??

“But if the wicked man turns from all his sins which he has committed and observes all My statutes and practices justice and righteousness, he shall surely live; he shall not die.  All his transgressions which he has committed will not be remembered against him; because of his righteousness which he has practiced, he will live.  Do I have any pleasure in the death of the wicked,” declares the Lord God, “rather than that he should turn from his ways and live?”  Ezekiel 18:21-23

If the wicked turns, how can he live?  Everyone still dies!  So what hope does this leave the Jew?  How is the Messiah going to bring age-lasting life to anyone?  Is he just going to replant the trees of life and say the all-you-can-eat buffet is now open?  But how could that bring back David or Isaiah or Daniel?
