Nah, I actually think she has a great point, if anyone has the right to say that it's her. She is the one who tried to accept her fate because she thought it is futile to resist it, and if she tried to reach out to them for help she would endanger them too.
Sounds familiar? Yeah, her case was also one where people's lives will be at stake if she reaches out to them, it would be way safer for them if she accept her fate, then none of the main casts will be in danger, but despite that MC reaches out to her and told her to forget about other things and asking her what she truly wants to do, what her true feelings are.
MC is in a very similar situation to the one she was in before and ended up with the same conclusion that she did before, accept that it is the best way to solve everything despite how he actually felt. What she did just now isn't really about her telling him how he should act, but more like throwing the word he told her back then back against him. Frankly, she is the one who is most justified to say that to him, considering she was in the same position as he was before he swoop in and told her that it is okay for her to be a bit selfish and do what she wants.
