This entire post is strictly IN MY VERY HONEST OPINION ONLY...
Can I just say that I cannot give Chad a pass. He lied to the police. He may have at one time been a "good guy", an "honest guy", someone that you cannot imagine would do anything like this, but... He lied to his family and to the police! He ran off to Hawaii with a new wife and has been "living it up" immediately after the "love of his life" died.
First, I am a member of the Church of Jesus Christ of Latter Day Saints (LDS). From my observation and experience, I believe that people can get personal revelation that may help guide them in their life decisions - prayer, belief, family, scriptures.... However, when people from our religion take it to the next level; unfortunately, I believe that they get corrupted. Especially in the last few years, I have watched numerous people of my religion get unhinged. Honestly, not as unhinged as I believe Chad is; but, nevertheless, they have become what I would deem as unhinged. For Chad to believe that he has lived multiple lives, to believe that he will deliver the 144,000, to believe that he has more inspiration than the leaders of a church that he says he believes in...
When a person of any religion begins to believe that they have extraordinary powers to talk to the dead, to talk to God, to understand things that we mere humans do not understand, I have to question what exactly they have done to "get" these special powers.
In my VHO (MOO), when Chad began to sell his visions, when money became a motivating factor, he lost whatever pure intentions he had in sharing his "gift". Greed... that is a big corruption. He opened the door for other influences to come in and change whatever good he had and even his "visions" became corrupt. I know his family and friends wanted to believe him. But, did they all know to what extent he was reaching out for monetary gain? Once corrupt in one area, I believe it was a slippery slope to corruption in other manners. I am sorry to those that knew and loved him, but I really believe that he did have an affair with Lori prior to Tammy's death. He likely justified it to himself since he believed that they were together in previous lives.
Finally, he may believe whatever lies Lori has told him, but he has to KNOW that something is hinky. Why in the world would he have told his family that she didn't have kids? Why in the world would he have reached out for living quarters in Hawaii saying they had no children? Why would he tell the police that he "barely" knew his wife and didn't know her phone number???? Because he is lusting after a beautiful woman and he is doing things that he knows is wrong. Sorry, not sorry, I can't give Chad a pass.
