But I don't really know, do I? Especially at this point. And I'm unlikely to have much further interest in the manly man.
I don't know how he was hurt, perhaps by his parents, the point being that it is passed down through generations. He passed it on down to his son, who last year terrorized his mother. So I suspect he was hurt before his son was born.
The meth is deeply symptomatic of self-medication and impulse joy-seeking (unable to postpone gratification). Hence him saying "I said to him 'Violence works. It gets immediate results'". People with injuries more or less along the psychopathic or narcissistic (unempathic) spectrum/axis are like that.
When violence is passed down psychologically to children it is a form of injury. As if a parent broke a kid's ankle and forced them to walk on it until it healed mangled and pointing to the side.
Whether it is an injury inflicted on a person, or congenital (in the brain), the person needs help coping, at least, and maybe remissive treatment if applicable. Whoever they are. So that these psychological injuries are not passed on down to progeny.
But Republicans, and the meth-addled dad is proudly claiming place in the Republiconned, the Republiconners are 100% opposed to taxpaid healing.
IANAP. I am not a psychologist. But I think the perspective is consistent.
