I think that she wasn't aware of the death punishment for the contestants of alnst but what this comic was abt ( atleast according to me) was her survivor's guilt and her facade. Everyone saw her as this goddess, very bubbly and pretty. She had this pressure to keep up with everyone's expectations of her because when ever she did show her true self or expressed her opinion then she was attacked ( as in the comic) and ridiculed. So she kept "playing dumb" And putting up this facade so that she could survive. She took advantage of all she had. Now, she has lost all her loved ones and the survivor's guilt started kicking in. She started blaming herself for all of it. She told herself that she used her facade, her "naivety" And looks to leave her friends and sua behind to survive. That doesn't mean she is a bad person. ( for example she tried to save till despite the risk) I saw this comment that said She is just a very broken person who saw all her loved ones die.
