To explain why deciding HaSatan is the boss of the demons is utterly ridiculous to the Jewish mind, angels live in higher worlds and don't see a separation between themselves and Hashem. It would be like no doctors or jobs here, just ask Hashem and poof, and you see the reasons why for everything. They have no free will as a result or the potential for any other desire than to serve Hashem in their state. Demons are things created technically last, even though it says humans were the last to be created, Hashem keeps demons around for their uses, but he doesn't seem to like to do that, so we don't give respect to them and say that. Demons are the lowest creatures, while humanity can intellectually perceive what angels do, that everything is Hashem, demons get their power "thrown behind Hashem's back", as Tanya explains (and is bringing older sources to do so), meaning their power is recieved indirectly in such a way as to keep them from seeing that it comes from Hashem. That's why Torah sometimes calls them "gods" (small g) as Tanya explains, that they think the power is their own and that they are the Hashem, because they are not made to perceive him or anything from him.
So we're talking about two types of beings that are utterly different in every way. The Catholic story that demons are really fallen angels is vastly to absurd to justify a response. Even early Catholic ideas like HaSatan runs the demons are a joke, the ray of light controls another ray of light? What's more, HaSatan goes around all day for millenia doing whatever Hashem says and nothing else because it's his job, and he doesn't have free will to choose to do what he wants, and if he did, the being he is only wants to serve Hashem. To make a dualist system where he's the bad guy running the bad guys and Hashem is the good guy running the good guys is a concept that is specifically forbidden in the written Torah, the prohibition against dualism, there is 1 not 2. HaSatan would hang out and have chats with King Solomon, and a demon attacked King Solomon. They're just opposite, and if already the angels consider us lowly, they certainly have virtually no regard for such beings.
