I think it depends on your values. Even though your mental state takes a toll, all you want is for your loved sick person to get better and not die.
Speaking from experience.
Miss Doh is just selfish.
So, no need for trust issues when you actually are loved.
To a certain extent, I think it's ok to wish for someone's death if them living will bring them so much more pain than dying. If there's no hope whatsoever of getting better. If they wouldn't be able to experience any joy for the rest of their life.
But for miss Doh, her father's illness was just getting in the way of her marriage.

I'm speaking from experience as well, though (not personal but from stories that I have heard) where people do feel completely resentful. It's mainly a myth that people are always altruistic, especially in the circumstances that Ms. Doh finds herself in (being saddled with the financial responsibilities and not allowed to seek support from someone else, whether emotionally or monetarily, as her mother and so many on here seem to believe, unfortunately). And as I told someone else we have NO idea what her relationship with her father was like before he became ill.

In case, Hwang falls sick and bed-ridden (I wouldn't wish that upon anymore, but IN CASE) after Doh marries him, will she think 'it would be better if he just died'??
I honestly thought that being forced to take care of a person (be it family or anyone) can push your limits to have thoughts like that and even go psycho and break a person who actually cared for them (hypothetically??) but now I'm having TRUST ISSUES
Also, Sooha and Taesoo happy times are the ones I live for *heart eyes with jealousy* (▰˘◡˘▰)
