Healthy or not depends on what you make out of it IMO.
Guilt and/or shame is always a sign that something is going wrong with your relation to the society and their standards. The opposite, total ignorance of the society, isn't good either though.
If one is able to find the fine line between guilt and ignorance, I am convinced CDing is healthy, because it's freedom and joy for your soul.
To get this fine line is the tricky part, and it will depend on a lot of outer and inner constrains.
You will have to give something to get this freedom and you will have to make compromises with yourself and the society.
