And Hell was first mentioned during the Medieval period. Sometime around the 1200s, I believe? The first versions of the Bible said that Lucifer was cast into Tartarus, where the Greek gods imprisoned the Titans.

The Bible itself is a collection of interpretations and stories across a span of hundreds of years. Jesus says that the Old Testament is null and void in the Bible, and then John later on says that the Old Testament is still in effect and that's not what Jesus meant and that he knows Jesus better than his disciples did, despite living over a hundred years later.

The King James version of the Bible was edited to be a piece of pro-monarchy propaganda that was published at a time when many monarchies were literally losing their heads. The history of Christianity can essentially be summed up as hundreds of years of groups arguing over whose head-canon is right.

Regardless of what you and I think of the 7 deadly sins, they are an established part of the religion and make this contrarian interpretation of the song work. Personally, though, I much prefer Jesus's mindset of throwing tables, beating up the rich, and telling people who blame women wearing revealing outfits for their own moral failings to tear out their own eyes so they stop.
