I understand how you're feeling. It just comes "over" me too sometimes but
@ab01 is absolutely right. They'll hate KK, and even distrust some of her testimony, but if they focus on the evidence presented, they should be able to see unequivocally who committed the actual murder. When they hear how he told lies about a lovely young woman to set up his "alibi", his collusion with KK in planning KB's murder and how she still cared enough about him to help with the cattle and pick up meds in the wee hours of the night for his tummy ache, and then burn her remains with KK at his side, they will absolutely hate/despise him. I also remind myself, the evidence we've seen is merely a sampling of what the DA has on him. There were 3300 pages of discovery.
Personally, I can't wait for PF's attorney to shred KK's character on the stand, but I doubt it will sway a jury to discount the mountain of evidence against him. And, since the preliminary hearing, I can't wait to see SF called to the stand! I'd like to know what she's hiding.
What makes me smile right now is knowing that baby K is in the loving arms of her grandparents, safely FAR away from the monsters that wanted to steal her.
