We're not saying that most-liked characters shouldn't die. They should completely kill everyone off at some point, in the most brutal way the possible. I think the point is, that people might get bored of everyone getting killed too soon. (possible comic book spoilers) I hope they keep Andrea around for a long time before taking her out. I'm not saying she should become inmortal, but there's a nice chance to make Andrea take a bigger role in the series.
~Goodbye, she quietly says~
