In the end Bill wanted to try to force the LDS church into recognizing PM and it was based on the principle. He went to his own church on Easter Sunday after he had stood up in the state senate announcing a bill that he wanted to put into motion regarding PM and apparently word had spread out to Juniper Creek as well as other areas what he had done and his church was packed, overflowing outside. He died after being shot by a neighbor, but before he died he asked Barb for a blessing. There has been tension between Barb and Bill this whole season regarding the priesthood and the fact that the LDS church nor Bill's church would allow women to hold the priesthood. He asked her for the blessing and after he died it showed him a year later sitting at the head of the table while his wive's hugged as Margene went off on a mission trip..non LDS. The writers of the show said they wanted to show that Bill fully believed that he would be with his wives for eternity. I have to admit I am a big fan of the show...some of it has been plain crazy...other parts a good story line.
