Maybe Hunter is all for destroying himself and his father. Knowing his family is a murderous treasonous pedofphillic extension of the age old satanic brotherhood. Their was speculation his wife was running from Joe when she had her car wreck and death, and maybe their is some other cause for the other sons demise. Maybe they are actually decent, and trying to escape the cabal one at a time. Hence Hunters descent into drug addiction. Anything to escape the horror of knowing who you are born into. So if he can destroy himeself, he can destroy his father once and for all.

Ehhhhhh dunno, long stretch, but maybe.
