For me, what is blatantly obvious in this sitch and a few others, is that the WAS is in a strong stance of believing what they are doing is in fact, right and appropriate.
I don't actually think an addict doesn't see the problem. I am more of the mind that an addict just denies the problem, pushes it down, buries it... often, with more of the same behaviour. It's their pattern, which is why they are addicted in the first place.
KD,
I'm failing to see the distinction you're trying to make here. Both of these types of people are in major DENIAL. Yes, I would advocate TRYING to get them to see what they're doing is harming both them and the ones they love, but whether or not I was successful at that, I would still do everything within my power to try to separate them from the source of their addiction, as soon as possible.
