I just think that's an inappropriate way to look at the problem. A lot of human behaviours that are persistent are not best viewed as a disease process, but as a learned, habitual behaviour that's satisfying some kind of need. Then you look at how this person could satisfy those needs in a more appropriate way that is less destructive to himself and to others. That's a better way to think about this.
The notion of “cure” applies to things like physical diseases, quite sensibly, but I don't think it's the way to look at this. What we're trying to do is reduce the tendency to hurt others in the pursuit of the same needs that the rest of us pursue but in more appropriate and less destructive ways. That's the aim of the programs. That's the way we think about it. We don't think about it in those psychiatric terms.
