What does Zohar say about Lilith?
THe Zohar talks about Lilith as one of the shedim- the weakest of the spuernatural agencies that G-d uses to affect the world. Lilith is identified as the sheid that G-d sends to induce miscarriages. An important factor to remember is that in Judaism (and thus in Kabbalah), no supernatural force has any free will- but only acts according to the will of G-d.
