You're right. When you're driven by a need like that, you're basically unstable on several levels. Every minute of your day is consumed in the where/when/who your next fix is coming from. You apply every angle you can to money and ways to manipulate it to your advantage. You look for loopholes in anything and everything at your disposal, and you can twist logic in some very, very, very unnatural ways. What was once immoral and seemed totally out of the realm of your comfort zone....becomes your norm. Basically? You spend your days conning yourself into throwing the things that ground you right out the window. I still think of those days and some of the crap I pulled and the people I knew...and my palms will sweat. I never killed anyone (or wanted to...), but had I kept going, I can right about bet that I would probably have ended up dead myself.
The people who deal this crap are not nice guys (or gals, as was the case with my primary supplier..). Two out of three are users themselves and sell to keep their habit running smoothly and a roof over their heads...but it's those sober ones you have to watch out for. They're the guys/gals who are out for the big money involved in this kind of thing....they don't use what they sell because it puts a huge dent in their profits-and they're looking for the money. Dealer A is looking to make enough to stay high....Dealer B is looking to get rich....
Yes, that's exactly it! An addict thinks short-term only. And strictly about the next high. An addict is not motivated by revenge, love, hate or any long-term benefit to self or others. They simply have no access.
Addicts are however in a position to be used by folks who have those kinds of motives. Important considerations in parsing out motive here.
The new tidbit about Gary opens up some new territory for speculation. While the arrest is kinda old (and wasn't something waived for successfully completing probation?), and he may have gotten clean, shooting up Xanax is pretty serious involvement. Not likely to have just gene cold turkey during 3 days in jail and then stayed clean. Really needs some serious rehab.
So IF Gary was an active addict, and the family was at least dabbling in enterprises connected to drugs and money (both powerful triggers for an addict), what might he have done (think selling and skimming profits or goods; theft of profits from other illegal endeavors), to bring down the wrath of somebody big. And might the rest of the family gotten dragged in to protect him?
