Well TODD, you've got a good analysis there for the most part.. I just don't buy the abusive father part. Most of us that have had real parents have been "abused" by today's standards. Yeah, he probably didn't do the chores around the farm a couple times and got his @ss beat for it. Big deal, move on. But no, being an insipid sociopath, he did what all sociopaths do, blamed everything but him. Oooh, it's his father's fault he is the way he is becuase those "woodshed philosophy" sessions were so horrible. It's the animal's fault, if they weren't there he wouldn't have had chores to be beaten because he didn't do them.
Same thing with his adult life, it's everyone else's fault he flushed his life. And being the rampant sociopath now, his behavior towards others isn't a surprise. It's typical for that type to act like your best friend, until they don't get what they want. Then they become violently angry. The slightest insult (to them, probably not meant as an insult, i.e. having a differing opinion is an insult to them) and you're now at permanent war with the @sshole because they think they deserve to be bowed down to. Their attitude is worse when it's someone they think is weaker then them (i.e. women) don't bow down to them. It's compounded by the fact that RIKA and our other little sis, constantly ruin his sh!t.
