I'm sorry I guess I didn't phrase is right. That ABSOLUTELY makes them IRREDEEMABLY PURE EVIL. It's definitely in my definition of pure evil. With what we have seen so far in the manhwa and what u gave us, the Roam dont give a rat ass about her safety. That's not why they "regret it". They only regret choosing the wrong one. The Roam can't get anymore glory with Lilia so now they need Annelie back. To continue the family glory. Not cuz they care about her at all
Nah you're making this conclusion based on "what we've seen so far in the manhwa" (incomplete information) and "what I gave you" (also incomplete information). I literally gave like less than 100 words from the novel itself.
Maybe you're right that the Roam family is only regreting because they "chose the wrong one" and they want the glory that Annelie's status can give them. But we don't know that for sure yet. The novel isn't fully translated, and I've barely seen what the Duke and Duchess are actually thinking.
I HAVE seen what Annelie's older(?) sister is thinking though, and the two have confronted each other (it ended badly btw.) Her, I could see being redeemable (aka grow into a better person), if she reflects on the confrontation later.
I'll change my opinion on the Roam family based on new information presented to me. Again, I'm not saying they should be forgiven (they literally put Annelie to death over a prophecy) but as of right now I still don't think they're pure evil.
Like I get it bc in that era reputation is everything but still you'll think about all the hours and yrs put into their daughter to train her into being the empress only to unalive her & replace her with the one who told them their daughter will ruin them....anyone educated should've seen that as a self-fulfilling prophecy. They should've stood by their daughter, since she was gonna die anyways and be seen as an amazing family bc reputation is important instead of replacing their daughter with a fraud. I haven't read the novel or spoilers but I believe the blonde knows the story thats why she was able to correctly predict the future. Now that the storyline is going in a different direction with the daughter being revived (and shes probably the og fl for all we know) the blonde wont be able to con her way back in.

Honestly, the Roam family isn't irredeemable.
BEFORE YOU SAY ANYTHING, I DIDN'T SAY THAT THEY SHOULD BE FORGIVEN. I'M JUST SAYING THEY'RE NOT PURE EVIL.
Lilia was churning out "prophesies" (read: novel spoilers) that were all coming true and predicted that Annelie would bring the downfall of their family.
Between the terminally ill daughter who was "prophesied" to bring the family to ruin, and the "prophet" who was ready to fill in her shoes, it was obvious which choice was the "correct" one.
The family has shown regret, snippet below.
---
"The prophecy said that Annelie would bring ruin to our family. But that hasn't happened."
"Because we put her on the execution block first."
Duke Roam's lips trembled.
If they had all been deceived by a false prophecy... The thought alone was terrifying.
"Before she could destroy the house of Roam... we killed her first. And now there's no way to verify that prophecy."
---
The family seems to think that Annelie would be safer with them than with the temple or the palace (MAYBE true) and that Annelie would understand their decision if they explained themselves.
Right now their mindset is "no use regretting or lamenting (they're still kinda doing this btw), just look ahead make the best decision for the future"
