I have little experience with pedophiles and rapists in particular but I do a lot of profiling and research on this matter. I personally believe that people have varying tendencies and responses to these tendencies. Some are just wired to be more attracted to younger girls or boys and have no boundaries as to their sexual relations. I do believe however that there is hope for anyone strong willed enough to defy their tendencies but it requires serious recalibration of thinking and slow reintroduction and reintegration to society. It will always be a lifetime struggle. Then there are sociopaths, ones who are incapable of moral distinction regardless of whatever medication or therapy he or she undergoes. Those people are beyond the control of existing structures and policies. We need more research on that.
