The woman is a real dummy to continue to associate with this kook and expose herself and her children to a nut-case like that guy. And why do you think he acts and reacts as he does? Could it be that he saw similar violence by the adults he lived with as a child?
Just look at what they're exposed to as children. And we wonder why such people raise another generation of children who, as adults, turn into predators who commit the same savage, unbelievable crimes against each other and against the innocent society in which we all live.
It's long-past time to get tough and stop being so darned liberal in our thinking and in our attitudes towards this kind of misbehavior.
