Lucifer was originally the name for the planet, Venus, in Roman mythology. That’s where “morning star”’ comes from. Because it’s visible just before or just after (as Noctifer) the sun rises and falls.

Early translaters used it for the name of the “Shinging one” in Isaiah.

Not everyone associates the name with a demon… that’s mostly christians and Christian off shoots.

So no, not everyone is the same as you enough to avoid naming their kid something you think is alway bad.
