The lore is actually unclear on that. Most seem to agree that Lucifer is a fallen angel, but it's never so much as suggested in the source material that Satan is Lucifer. Lucifer is actually only mentioned one single time, in an old testament verse. The other dead kings are making fun of the king of Babylon for failing to defeat God and dying himself. As the king of Babylon is dying, the other dead kings say he has "fallen from heaven" and call him Lucifer. It seems implied that Lucifer and/or the king of Babylon are being compared to ~~the sun~~ Venus, the "morning star", and the second brightest object in the sky behind the moon [added this part in an edit], and I think many have interpreted this as to mean Lucifer was an angel that tried to shine brighter than God and this was cast out of heaven. But it seems like most of the modern depictions of Lucifer have no basis in biblical canon. It's all people trying to extrapolate from one single time the name Lucifer was mentioned while dead kings make fun of a dying king.

I mean I feel like undoing all creation every time I fall or stub my toe, too. Sure, we all do. But geez, it's a figure if speech! An in the moment thing!

"anti" also doesn't mean opposite, it means against. The roots of the word, tracing back to the Greek, means against. As it does in French and it's Sanskrit version. All forms of it mean opposed to. This is why language is important and some checks should be there to counter the "language is malleable" argument that people use as an excuse to not learn how to use words correctly. The idea that anti means opposite has been around as long as I can remember, and definitely longer than that, but it drastically changes the meaning of words.

Still he is often portrayed as the evil counterpart of God, which is as opposite as you will get

This is the kinda of rebuttal I like to see.

Translation after translation after translation is how we ended up with the such an absurd story.

What an amazing rabbit hole to go down. Thanks for teaching me something new! Fascinating religion with quite the history.

It's "Lucifer." It means "Light Bearer."

My favorite (probably inaccurate) point about the name "Jesus Christ": the name "Christ" means "anointed one", as you said. People were generally anointed by having oil poured on their head. "Jesus" is just contemporary form of the name "Joshua". So in another life, "Jesus Christ" could literally be translated as "Oily Josh".

i'd like to learn more about your religion please

why the god would give a freewill to the humans but not the angles?

Angles do have some free will, but only to a degree

the christian god also punishes humans for 'misusing' their free will

Because angels are only gods army of mindless robots.

It's not that they're incapable (at least not all), they just turn it off when it comes to religion.

My parents are staunchly evangelical to this day, and I've heard my father use logic and critical thinking on multiple occasions, even identifying things like non sequitur and Occam's razor when it comes to following a train of thought through. I've literally witnessed him using the same logic atheists use to disprove islam.

Unfortunately they're trained from birth to believe that...

1. Doubting the Bible is heinous and will put your salvation in jeopardy.

2. Everything that contradicts the Bible is just a plot from the devil to ruin your salvation.

Once you ingrain those ideas into a very malleable 3-4 year old mind, it's incredibly difficult for them to remove their emotional attachment from the specific religion they're a part of so that they can use the same logic they employ on other philosophies into their own.

It's like a mental block, or a thought virus. They terminate any and all logic when it comes specifically to their religious beliefs (and politics, because it's the same thing for modern fundies.)
