Trashta is like salt. It may look like harmless sugar but it salt.
I think you can't compare Rashta to that villain. Since she's not strategic woman to begin with.
Rashta is stupid and has brain of a chick but her level of threat is uncontrollable and much more destructive not only towards the FL because she has a FREE GO.
She is not a strategic woman but her power in court depends on the emperor saving her butt.
Even if the event is clearly fishy if the emperor says Rashta didn't mean it the people can't say otherwise.
My point is Rashta is a different type of threat that is not dramatic plotting in court, she's more like when you decided to give the power to an aggressive mentally ill child. Plus she's manipulated by almost everyone thus THEIR level of threat is incapsulated in her because she herself is being blackmailed by them.
(metaphor is a high ranking politician that is a puppet of mobs and the mafia)
And no matter how bad it gets you can't say anything since the emperor will silent you even if you show the truth. Pretty much that's what Navier went through she was trap in that situation of being unable to say anything since from my quest in this story line the emperor has absolute power.

Ooooh ho ~
She is evil.
No doubt about it.
Recalls scene where in the same chapter she keeps screaming" I didn't do it! I could never kill anyone" and "I should have killed them! I should killed them all. Damn her. I should have grab her by the hair and punish her(surely death)" or scene where she intentionally put her maid in life threatening position and threatened to cut another maid tongue for amusement. Or when she planned to make one of maid become like a slave and thus eventually even sex slave.
Where I live harming someone physically and amusing yourself by torturing people is called being evil and a danger to all.
(unless the sadisms is has consent of the receiver of pain but that's another story).
Unlike the villain of Lady to Queen.
Rashta is a danger not only to the FL but to the kingdom. she was a slave that just started learning writing... She can't be trusted with politics.
As seen how the kingdom defenses have been compromised because of her negligence to the point even the emperor and his adviser don't known how to fix the damage
I agree that reading this is very frustrating but in my opinion, Lady to queen manwha is even more frustrating than this. The villainess in that manwha is like so dangerous and scheming, she plans to sabotage the FL reputation and life every chance she gets. Im worried for FL life like every single chapter. Stupid Trashta can no way be that evil and cunning like that villainess.
