It's possible.. (Jmo)
I think it's possible that after growing up with Lori and then witnessing her sociopathic criminal behavior as an adult, AdC came to know that his sister was literally the wicked witch of the west.
AdC watched as Lori defied the courts (Tylee custody) and perhaps plotted to harm and/or kill JR. Then he watched as Lori further brainwashed and corrupted his brother AC and began to use AC as her own personal enforcer and hit man. He watched as Lori and AC plunged deeper and deeper into the hubris and insanity of a doomsday death cult.
I think AdC was and is good people. I think CV, AdC, and BB all improbably ended up on the same team - knowing however that no one would believe them. AdC knew enough about Lori and AC though to take CV's (and later, BB's) claims seriously. AdC believed CV when CV told him that Lori was deluded and insane, that she was part of a dangerous cult, that she was having an affair with the cult leader, and that CV's life and the lives of the children could possibly be in danger.
When AdC learned that CV had been killed by AC, I think he suspected it may not have been self defense. When AdC later learned that Lori and AC had fled with the children to Idaho (and then when he possibly heard about TD's death) he may have begun to truly believe that the children's lives were in danger. But by then, they were gone.
AdC may have also pieced together info about MG, JM, and others. After the children disappeared, like BB, I think AdC began to suspect that his own life was in danger.
So maybe AdC decided to put an end to it. Maybe he decided that the best defense was a good offense. While AdC may not have known where Lori and CD were, he may have known where to find AC...
The above story should rightly be considered outlandish fiction. But this whole case has been full of what should have been considered outlandish fiction - but instead turned out to be all too real. In this fantasy, I'd like to think that perhaps AdC defended himself and became an avenging angel of a different kind. Hopefully LE and the courts will do the rest.
