I feel like the way these choices are supposed to be interpreted is almost like a manipulation of Carver. Trying to get him to believe you'll be on his side instead of the others to throw him off. I can hear it in Clementine's tone.
the decisions don't matter that much in the end because the Story still stay the same would have been cool if you could have really joined him and had an alternative story because of it but it's still a great game
That would mess up the story and Clementine would just be evil. It wouldn't even add up. It's like saying you want go with Mike and Arvo but they still completely abandon you.
