I would agree that she's grown into the image she projected (one of villainy) but I don't think she's lost her humanity. Also I don't think Jeremy could straight up murder people especially since they're on neutral ground (take this with a grain of salt) just wound greviously, and if I were her I'd also let annoying people who constantly objectified me suffer.
agree i don’t think she lost ALL her humanity at least she has a lot more then dions but it did decrease a lot she started resembling her father more then her mother or how right before the ml escaped she lead his people to the dark forest to be killed for no reason and told him that they were safe. oh and ya i think jeremy wouldn’t just go around murdering people unless it has to do with Roxana since he’s really protective over her, like how he killed the maid in the yearly house’s meeting only because she was curious of how Roxana looked like
in the beginning she was only pretending to be a villain, she was scared of dion, and was more warm with jeremy, she was even disgusted in her self when she had to pretend to be a villain but as time went by she stopped pretending to be a villain and because and actual ACTUAL villain. she started doing the stuff she was disgusted doing for fun, she became colder, and changed so much in 3 years to the point there was barely any humanity left in her, i wonder how is the ml gonna react to how she changed after leaving. as they say either die young or live long enough to become the villain
