“Often the biggest critics of the ideas of Heaven and Hell are the Jews”
Wrong. Hell is taught in the Talmud.
A lot of argument about that.
Most Jewish ideas about the afterlife developed in post-biblical times. The Hebrew Scriptures themselves have few references to life after death. Sheol, the grave, is portrayed as the place of the dead, but Sheol is a metaphor for oblivion and not an actual place where the dead “live” and retain consciousness.
