It’s simple word association. I’m aware of the Latin translations. I’m also aware that most people are not going to think about it too long, and immediately going to jump to conclusions. They also believe in Bigfoot. What end of the Bell curve are we talking about, here?
I get things like “enlightenment”, etc. But the average person (at least in the US) that isn’t already Catholic has a strong possibility of already being told they aren’t real Christians, and isn’t going to know or care about etymology, and will assume it’s Lucifer. They could call the main character Satin after the cloth and it’s have the same effect, even though they aren’t related.
