@Yuri_Fanatic_ As far as I understood, this was a follow-up to her/his initial excitement over being able to let the new capture target do the rest of the work for her.
However, she/he probably doesn't like the idea of walking over corpses. If he/she did leave it all to the new capture target, she/he would knowingly let her die "just" to escape this story.
Also, if this "game world" continues even after the ending, then he/she would have to deal with a heartbroken protagonist.
Granted, most people would rather leave this "game world" with a bitter taste than to spend that much effort saving someone they won't be able to meet anymore after successfully escaping.
