My overall point for offering my own experience with very, very close friends who have
fully survived their addictions (with them and their children-now-adults being quite normal and released of their pain - I have particular intimate knowledge of and participation in their paths to recovery) is that such cases are not always and definitively lost causes and to immediately dismiss every case as such does a disservice to society overall. We are better than that as a society.
Do we simply stop attempting to break through the defensive, sometimes overly-scarred exteriors of addicted personalities and leave them to fend for themselves and wallow in their downward spiral without discovering reasons why such addictions occur and what makes the lifestyle concurrently destructive and attractive to them,
and then bash the living excrement out of them when their situation presents with tragic result, without ever having attempted to lend a hand?
Remember: they are addicts. They are not thinking clearly. Simply attributing to them their knowing of "right from wrong" does not qualify the claim "they know what they're doing, they made a choice, they can unmake the choice."
NO. It is NOT that simple. They are addicts (addictive personality also includes non-drug-related dependencies). They can not control themselves. They will continue to say they need help. They will say they will get themselves straight. They will refuse offers of help. They must be broken, hit rock bottom for them to even consider a mildly serious attempt to getting straight. This, unfortunately, typically leads to a severely physical and / or mental injury that overpowers the desires to satisfy the addiction. A fear must be extinguished (fear they will not succeed), a realization they can survive without addiction, that being straight is a high in and of itself and .. the very odd aspect to this: *feeling straight* must satisfy the addictive desires. Replacement therapy is what worked for our friends.
I am not a "bleeding heart liberal" (wow, does that age me?

), as some might be thinking and I can almost feel anger directed at me, emanating through the monitor. I am not making excuses for their behavior. I have no sympathy for those who unequivocally and continually refuse to seek or accept help of any degree, especially those who have children. And yes, at some point you just have to accept a lost cause for what it is ... but, IMO, NOT before every proper attempt has been made to save that person regardless of what tragedy (that they are not DIRECTLY responsible for, i.e.: murdered their child or spouse) might have occurred during their sickness.
For argument's sake, let's say a "GT" (uh-huh) might be a lousy, addict mother, her daughter murdered at the hands of a 'family friend', a someone whom the mother thought she knew to be a nice guy even though she knew he has a criminal record that screams "I AM DANGEROUS". So, we comment, "GT is scum!", "GT is evil!", "GT is a baby killer enabler!" ........ I do not see a productive value in any of it, except maybe to fuel the anger coffers of people who might themselves have been victims and simply want to destroy the "evil addicts".
