(A TL;DR here for a sec. Basically everyone's on a deadline. Kill/change Sougo before Oma Day. And Tsukuyomi and Geiz are hard-pressed to meet that deadline, but their roles have been switched (at least until this episode).)

....But I like to think that, with what we're given now, that her witnessing Sougo's first true step towards Oma, especially after his freakout back in 16 (which I feel reaffirmed her faith in his not turning evil), made her become a bit more irrational and hasty. Which I think is reason for how fast it happened.

To her, I think that Oma Day could, literally, be tomorrow, and she'd have no way of knowing. So she starts pushing Geiz's original goal, leaving Geiz between a rock and a hard place: kill Sougo or trust in him?

When, let's say, a student, waits until the last minute for a deadline they want to do good on, they change up their whole lifestyle and fixate on that deadline until that deadline is met and taken care of.
In this case, Tsukuyomi is the student and Oma Day is the deadline.

And seeing as how Oma Day is literally only months away (as mentioned in, I think, episode 15), her few weeks with Sougo clearly haven't changed him in her eyes, with the advent of Zi-O II.

Mind you, this happens shortly after the meeting of Sougo in the future. To see him accessing his future powers now (e.g. time rewind and future-making dreams) makes her more fearful of the deadline. Also, Sougo said that he "accepts his good and evil sides"; make of that what you wish.

(EDIT: To add to this, Tsukuyomi trusted Sougo a lot. And this trust was, in my eyes, solidified after Sougo's breakdown and later dedication to give up being a king.
So to see him embrace his Oma powers (and overkill via Zi-O II) basically destroyed that trust, leading her to become more spiteful towards him.
He was never the pure cinnamon roll she made him out to be- he always had the ability to become Oma, and so her efforts were also a waste)

Back to Geiz and Tsukuyomi, though... This is the "Hourglass Plot" trope being applied.

Tsukuyomi starts out not wanting to kill Sougo, and grows to really believe he's a good person; but after seeing his first step towards Oma, she panics and feels betrayed, and starts to turn on him.

Geiz initially wants to kill Sougo, he eventually learns to love the guy, and was recently caught in a 2-1 vote in favor of killing Sougo.

It's just now that Geiz turns on him for real, due to having his resolve shaken and solidified.

I think both reactions are very reasonable. But they could have been done better. That being said, if you read between the lines, their actions make a lot of sense. At least, to me they do. They might not make sense to anyone else...

I probably should've worded it better but I was agreeing with your interpretation.
