Is Izabael good or evil?
There is no good or evil save what happens to be “good” for you in the moment. In that sense, Izabael is entirely good since she opens up your intuition to the divine, which is to say she opens you up to the joyous sensuality of spontaneous existence. As far as her being a “demon”–it’s an old fashioned term so I prefer to use “genie-demon” as it makes implicit the connection between the Arabic “Jinn” (or “Djinn”) and the demons of the Goetia. Izabael is just a spirit, not a religion. In Christianity she could be a “Saint,” or a “Loa” in Vodou.
