I'm going to be somewhat pedantic and answer the question put forward of this thread and not that asked in the post itself. Therefore, my answer is Ashley Williams. I may have kept you alive during the first game, but seeing that you came back as whiny, narrow-minded fool of a woman in the second game, you have to go, I'm afraid.
Also, I may like some of the ME2 squadmates less than the others, but not so much that I'd need to have one of them bumped off.
