I do like that Seocchi is essentially going "yeah I fucking tried you know, and turns out being a goody two shoes doesn't matter if Prez still wants me dead. So I'll show him, hell I'll show everyone just how evil I can be"
It makes her heel turn fun, and like yeah, if you try you damnedest and then the idiot arbiter decides you have to die anyway. Then redemption isn't going to save you so you might as well send everyone to hell with you.
"If I can't fight fate, I may as well spit in its face as I go down."
Sometimes all the good intentions in the world can't stop that world from using you as its punch line. May as well give in and let the ride take you where it will at that point. Prez is still a creepy scumbag, and he's actually still more a villain in this than Seo is as far as I'm concerned. I sympathize a lot more with her than I do him, certainly. Dunno if that's gonna be an unpopular opinion or not. I have a feeling it's mostly determined by how much each reader personally relates to her mentality here.
