There is a big difference between disliking a player due to interactions outside of the game, and deciding to bring that dislike into the game as OOC actions. Do you want to force characters to never act against another character, whenever the two players might have had disagreements, no matter how much IC justification there is for it? The few members of the rebellion I have experience with go to great lengths to separate IC and OOC, and I doubt they would let their personal opinions of another player influence the actions of their characters.
