I believe KK was more involved than she admits in the planning and the "why" that has not been addressed. I believe the prosecution has avoided asking her how the plan came about to kill KB in the first place. There had to have been a conversation. Look how much PF has shared about the actual murder with her. That said, I wish she didn't have as much of a deal as she was given, but I've decided to see this from KB's perspective. As a mom, her biggest concern is/would be the safety of her daughter and her having a loving family surrounding her. Even "above" justice for herself. So, whatever is needed to best ensure that PF remains far, far away as she grows up is the best "justice" for Kelsey, IMO. KK has questionable character, no doubt. But I don't believe she'd be caught up in something like this again. On the other hand, I can absolutely see PF killing again. Little KB needs to stay tucked safely in Kelsey's family for as long as possible. Forever would be awesome.
