If he's really struggling with alcohol than I feel very bad for him. An internet msg board isn't really the place for discussion on it, but my father struggled with alcohol. Not as in he went out gambling and drank a lot but as in he wouldn't leave his bed for weeks at a time, unless it was to get more booze and went through the detox and rehab process half a dozen times before he finally got clean.
I can tell anyone who has not truly seen this kind of thing first hand, it is one of the toughest things a family can go through. I feel for AI's family and hope he finds some kind of peace. People have all kinds of motivation to self medicate, whether its alcohol, drugs, or whatever. I won't deny that it is wrong, but I will absolutely dispute the "he made his bed now he can sleep in it" kind of thinking. You will never find a person in your life who feels more alone, worthless, and self loathing than someone who is really deep in the clutches of alcoholism, and if you have really seen it, you know that thinking "well if they don't ask for help screw them" is just blind thinking.
I don't begrudge anyone that line of thought. I went through a whole gamut of emotions when helping my own father and my family though his addiction. I'm just saying from experience, there are many more reasons these people don't ask for help then pride or hubris. Once I understood that, there wasn't anything left to feel besides pity.
