Good points all around. Regarding "Stockholm Syndrome", a case could be made that Hannah is in hat situation but she's by no means a victim, so I hope there is not the attempt to claim that for her. She put herself in that situation and willingly stayed in it, regardless of the reasons. At some point, if she was truly worried about her long term safety and well-being she could have done something different (even leaving her 'husband' to his self-deserved fate with Orlav) than to willingly allow herself to be degraded until she felt she 'had to' in order to 'survive'. This is *especially* true when she deliberately pushed away the man who was willing to get her the 'affection' she apparently misses now. She purposefully chose those actions, and now she has to live with her consequences for years and decades to come.
With that being said, I have not actually played the purity path in KC so I wouldn't know what excuses Hannah has brought up to try to justify her inability to act and get out of the situation she was in *before* she reached the level she is now. Which goes back to the initial argument that on some level Hannah enjoyed her treatment and stayed in it willingly, even if she tried to tell herself she didn't, and that makes all of the other labels 100% correct no matter what excuses or justifications people may attempt to add to her situation to make her some sort of lost 'heroine'.
This is exactly the same path Katie is on if she makes decisions that degrade herself, both for short and long term consequences. The only time there might be some justification was if she was literally tied up and forced to do things (i.e. had things done to her she couldn't stop or prevent) or if drugged or otherwise incapaciated. Otherwise she is deliberately making choices and I expect the dev to take her down a 'worse' path than Hannah, and she'll deserve it.
(BTW, as someone who works in the medical field, it is especially difficult to justify Katie's actions because there is zero chance her mom wouldn't get the surgery she needed if she went to any Emergency Department in the US. I don't know how it is outside the US but here we have a little law that requires hospitals to treat people, regardless of their ability to pay. Apologies for that being a side-note and possibly off-topic, just makes the story a bit unbelieveable.)
