Alcoholics may not have the power of choice, but the only way they can get any sort of control or desire to seek treatment is to experience the consequences of their choice (which they have no power over). I am in no way suggesting they be given special treament. If anything, they should be held to stricter standards as their own actions could not only kill them, it is a danger to others and a drain on society.
They can no more stop drinking than they could stop breathing. It happens, but usually not without some sort of upheaval or treatment which is another form on upheaval.
I worked the night shift in a residential treatment center for advanced alcoholics while I was in college. We had this one guy who was completely wet-brained. Needed help feeding, hygeine, going potty, dressing, even eating to some extent. You know the one thing he could still do without any aid? Go get alcohol. I'm not kidding. We had to kick him out for going to buy liquor.
