I don't think she did. She tells us that the stash was hidden and nobody knew about it. And she tells us that purposefully set it up so that while everyone else was going up she would go down. Again, this was planned, deliberate, premeditated CJ. She set up a solo contingency and purposefully didn't tell anyone about it. This is the same as the Burt comparison. There is a difference between being in the heat of the moment and everyone is panicking and so it is too late to speak sense or logic into people. It is a very different thing to have a premeditated plan of self defense and not share that plan with anyone. These are the things that make CJ who she is... Everyone may be on his/her own once the crap hits the fan and zombies are everywhere, CJ plans to be on her own well in advance and stacks the deck in her favor, everyone else be damned.

Isn't this the same thing Bill did by stealing ammo and food and stashing it for himself? Only difference between CJ and Bill is when it came to the end, like Michael says, Bill was there standing with everyone else and ultimately gave his life for the group. It is these minor differences why CJ is so disliked.
