KC did better for herself than JB did-At least she did not make excuses.
I wanna swing KC around by her ponytail, don't get me wrong, but I do believe KC has always been regretful (or as close as she can get) about what she did to AH. She doesn't regret stealing the money, she regrets messing with someone that could have stayed pleasantly on the perifery, someone who was not invested enough in KC for her to hurt like she did-KC prefers to save her nastiness for those that she has more than a superficial relationship with, not nice passers-by like AH.
She expressed this to her mom in the jail visit, and I noted this was the only time she straight up owned up. Her ire is for Caylee, CA, and GA and LA and JG, RM and even AD-AH was not supposed to be part of the hate and KC wants to clear that out of her concience ASAP.
