I also believe that when I start to hate the addict I am buying into evil thinking too.
I couldn't agree with you more!
Only my faith has kept me sane!
I, personally, don't believe in a "devil" that is outside of our own evil side of the self. We are all, each one of us, holy and profane. But, whatever part of ourselves that we feed, grows. Sadly, the addict feeds into the contempt for the sacred side of their self. Recovery allows them to rediscover the sacred part.
My prayer is that our addicts will once more discover their sacred self.
Shalom!
