As far as I can see, he is mentally ill, and an alcoholic, so at least in the UK, he'd get some form of benefits still, while the state and his doctor would try to help him get himself sorted out.
From that point of view, you're doing him even more good by reporting him, and barring him, well it won't stop him drinking, but if your bar is his favourite, it may make him cut down some, and even if not, you can feel safe that you did what you could to help him, despite him doing all he could to make you not want to.
You've done nothing wrong, and I don't feel taking that step would be wrong either, I feel you're stuck with the option of doing him some good, but knowing it'll be hard on him.
Again, it is from the UK perspective, but there's a form of welfare in most countries is there not? Surely he'd be able to get some short term help at least.
