Some Good Omens thoughts under the cut that have almost certainly been done better by others. (It's not about the finale, it's about goats.)
There are two moments in this show that explicitly involve goats:
Both times, the goats are paired with/mirroring children:
Flood scene: Young goats and small human children running past the enclosure while Crowley says in horror, "Not kids, you can't kill kids!" ('Kids' being a word for both small human children and baby goats.)
Job minisode: Crowley again, "I long to destroy the blameless children of blameless Job, just as I destroyed his blameless goats." (He does none of this, but he lies very convincingly about a) wanting to, and b) doing it.)
Obviously, the repeated 'blameless'-es were for sentence rhythm, but it's still has the effect of implying that, for Crowley, human children and baby goats are ontologically the same: not to blame, not their fault, not responsible for their actions. And he lumps in Job with them as well, in this instance, because for Crowley, the blame is all on God. (Not, interestingly, on Satan.)
So we have goats. You know what we don't have anywhere in this show, at least not that I can recall?
When the Son of Man comes in His glory, and all the angels with Him, He will sit on His glorious throne. All the nations will be gathered before Him, and He will separate the people one from another, as a shepherd separates the sheep from the goats. He will place the sheep on His right and the goats on His left. (King James Bible, Matthew, verses 31-33)
The sheep, in this parable, being the righteous, and the goats being the damned. The sheep get to join Jesus in heavenly glory, and the goats are condemned "to eternal hellfire"into the eternal fire prepared for the devil and his angels." (Matthew verse 41)
But there aren't any sheep in the Good Omens 'verse.
I'm deliberately not talking about the finale here, because whatever anyone thinks of it, that was not the Second Coming that the Metatron had intended, so the Book of Life and Michael's breakdown aren't really relevant.
That said, I do find it interesting that Hell is so very, very crowded, and Heaven so very empty. That Hell is overwhelmed with admissions and clearly can't get funding for any improvements, while Heaven's corporate team swans around in gleaming palaces and talks on ethereal iPhones, and is deeply unconcerned with human life in general.
There aren't any sheep in the Good Omens universe. There aren't any 'righteous' people. There are only goats. And ultimately, they're blameless.
(Yes, I know The Good Place did this before Good Omens even aired, I am ignoring that for the sake of Rambling About Things.)
