I don't know if batterers are considered sociopaths or not, but I hope that someday they truly treat abusing someone's animal specifically to hurt them as an assault on the owner, especially when fathers and step fathers do it to their children. I think that this can cause some separation in kids' minds where they learn never to become attached to anything because it will be used against them.
