Lucifer has a connotation that most people could ever get over.
For myself, I don't care how much I loved a name, I couldn't name my son anything that would lead to a lifetime of mocking and ridicule. The child has to live with their name their entire life, not the parent. I don't even think a child could be baptized with the name
Lucifer, so the name itself would probably be seen my many as mocking religious beliefs.
