@tip390 people are mad at her because they don't freaking understand trauma, just that fact that you and quite a few others are saying,"trauma or no trauma, she is wrong", shows that you guys knows little about trauma.
You guys are always too invested to the MCs of the stories that you forget that other points of view exists.
"Afterwards, she then goes to blame the MC for being "too late", like after saving money all that time she would have bought her freedom,been broke, and still reach the EXACT same conclusion but be worse off because of it."
You want to know what's wrong with this argument? This is the point of view of someone who has never experienced a despairing situation in which you have no one to help you out of, but your own self. When you're left alone for too long, your misery and loneliness turns into aversion of others, she's so used to people ignoring her plight that she doesn't want people to help her anymore, to help her now after all her suffering, is the same as humiliating her.
You were holding strong for so long, trying to solve your own problems and almost acchieving that, when someone else uninvited solves all your problems for you, this is the same as having someone call you an incompetent, a failure. Her reaction is anything but illogical.
Rather, people hating her are the ones being illogical, because they cannot relate to her experiences as they are too busy thinking about "her profit" or how the MC saved her so she should be grateful and not lash out at him.
Have you ever read a story in which the MC will try to help someone, but another character stops him and tells him to not be so irresnponsible?
Most people I know cannot understand why this character says this, but this entire situation here is an example of that. When you try to help someone who didn't really ask your help, you are actually causing them more suffering than helping. Of course, not everyone will have this kind of reaction, but some people NEED to solve their own problems themselves, solving a hard problem can be a relief to some people, an acchievement that will give them strengh to continue, when you rob them of this acchievement it's the same thing as pulling the rug under their foot. Not only that, helping people irresponsibly will not allow those people to have a better life, if you give someone food one day, you'll only solve that day's problem, the guy will once again fell hungry the following day but you won't be there to help him.
This is the main reason why I always try to ask people to stop using relatability as a way to understand a story or character. When you use relatability you close yourself to other points of view, it becomes way too easy to ignore other character's plights and misjudge them as villains or traitors. There's something called imagination, and this is what you should be using when reading a book or manga, this together with logical thinking and empathy will allow you to read a book with way more details, allow you to change points of view between characters and reach a conclusion that is closer to the truth, than just keeping your vision biased though MC lenses.
The whole argument "this is just fiction, she is not a real character" cannot be a more harmful way of thinking when reading a book, the magic of a book is that it's wrold and all charcters that live in it are alive and they need to evolve. When you choose a pov, read following that pov while comparing it to your own experiences, this is a problem because other people reading the same book have differnent experiences that are actually closer to other characters, and they too will have their own bias. Now, when you read freely, while asking yourself why is it that each character reacts the way they do? You then start looking at info you'd usually ignore, and the actions of certain characters finally starts making sense, all of a sudden there'll be no more, "I just want this arc to end" or "this development is boring"(of course when it's due to bad writing then yes, you are right for wanting to skip things), you'll treat secondary characters with more respect and find some reason for them to exist within the plot.
Anyway sorry for the rant, but this is neither the first, not the second time I see people misjudging a character so badly. It got a bit hard to ignore.
