I kinda hate it when the antagonist is like this. I don't condone her actions, I that she went so low to achieve her goals, it's just that she was selfish in her means of survival and desire to live better.
It would've been interesting if there wasn't the isekai angle (that didn't matter), and Angela didn't outright set out to sell her to a brothel and it was just something that happened while she schemed for money and power enough to pretend to love the prince. But that's just me.
