Who would be the best people to ask? The followers of the religion that originated the concept. Judaism. I will show you a picture with a quote of one prominent jew and what he had to say. And he would have no reason to lie about it. He said their god was lucifer. He also said that most jews don't like to admit it. I take this to mean that most jews know this. They just don't like to admit it. So if you aren't "anti-semitic," you must be pro-lucifer. Also, I have heard of jews who cause their children to "pass through the fire" to the deity morlech. Apparently it is allowed in the talmud.
