I don't really see this question as very valid. Why I saved Carley had little to do with her being a crack shot. The reasons why I attached to Carley was because she was the one who ran out to save my group when we first came to Macon, she saved me from the walker in the bathroom, she established herself as trustworthy early on with Lee's secret, she showed empathy towards Clementine along with the group and she was with me every step of saving Irene even though it was not her choice.
I think you need to rephrase the question/answers or add a couple other options. The current options are just making an assumption that is counter productive.
