They are drug/sex addicts cause Joe is a sex addict & a heavy drinker. He has said if he gets "Too Drunk" and there's children nearby that he "Can't Control Himself". I think Beau was Joe's Favorite and he made that clear to the rest of his kids. They All did whatever Pops wanted/needed of them to Earn his love & acceptance. In the process he put them All into emotional/mental hell. Who Knows the depths of perversion he made his children to go through?
