If you take the "labels" completely out of the picture what you are left with is the undeniable fact that some people feel more compelled to drink than others. It's very hard to argue though that "compulsion" has the power to override free will or the power of choice.
The devil does not assign special tactical alcohol control demons to make sure that each drunk keeps his/her blood alcohol levels topped off. The transition from sober to drunk is always a choice, might be a choice corrupted by the pull of addiction but it's still a choice.
