Yikes. It just occurred to me: what must KK's husband be thinking right now? She helped her lover rid himself of an 'encumbrance' (and marriage and property weren't even involved). Would PF have been willing to return the favor if KK had asked?
No. PF is all about PF. He's not going out on a limb FOR ANYONE
It sounds like all the liasons PF and KKL have had involved her going to him. Not him going to her. Clearly KKL has some very severe personality disorder, but PF caught on that she was so desperate for him that he could even discuss solicitation of murder with her. To the point that she would travel 1600 miles to do this. Not once, but 3 times, and then get her to do the heinous cleanup. Each time she made the trip to WP, it only made her compliance and devotion to him more apparent.
I'm not saying she came up with the idea of murdering KB, but it must have been more and more apparent that she was the only person PF would ever find who would do this for him and he had to use her.
He's on the Sociopath/Narcissist strata and he would never do anything for her. He knows exactly how weak and desperate she is. He CHOSE her because of this.
