I think there are few sins that are "fixed in cement" and I think compulsions can be helpful to us sometimes, serve a "healthy" purpose. I think God is all for our health and well-being and does not judge us "sinful" nearly as much as we might. Where something we judge to be sinful helps us, I don't think God judges it sinful.

Isaiah 55:8 -- For my thoughts are not your thoughts, neither are your ways my ways, saith the LORD.
